44 00:03:27,000 --> 00:03:33,000 Cryptozoologist Cliff Berwickman, one of America's leading bigfoot investigators, 45 00:03:33,000 --> 00:03:37,000 now has his sights fixed on finding the monster of the lake. 46 00:03:41,000 --> 00:03:46,000 His first stop is the Lake Southern Shore, close to the village of Kokonok. 47 00:03:52,000 --> 00:04:00,000 I'm Cliff Berwickman, and I am in Kokonok, Alaska, on the shores of Lake Iliamna, Alaska's largest lake. 48 00:04:00,000 --> 00:04:04,000 In some places, this lake is over a thousand feet deep. 49 00:04:04,000 --> 00:04:08,000 There's no telling what could be swimming around in the bottom of this lake. 50 00:04:09,000 --> 00:04:12,000 Cliff is here to meet the latest eyewitness. 51 00:04:12,000 --> 00:04:16,000 It's none less than the borough manager, Nathan Hill. 52 00:04:18,000 --> 00:04:26,000 On this beach, one afternoon in 2017, Nathan was one of a handful of people at this very spot, 53 00:04:26,000 --> 00:04:29,000 who witnessed the monster out on the lake. 54 00:04:29,000 --> 00:04:37,000 So, Nathan, the reason I came up here is to investigate some of the stories about the creature that lives in the lake. 55 00:04:37,000 --> 00:04:39,000 What's your experience with the creature? 56 00:04:39,000 --> 00:04:43,000 It was a calm day, and as I looked out, and I saw something in the lake. 57 00:04:43,000 --> 00:04:49,000 And there was at least half a dozen people that had gathered around to see what was out there. 58 00:04:49,000 --> 00:04:58,000 And at that time, I had my cell phone out, and I was recording in case something was to surface. 59 00:04:58,000 --> 00:05:04,000 Probably somewhere between three and five hundred yards off the beach, there was something that made some pretty big wakes, 60 00:05:04,000 --> 00:05:09,000 and everybody there witnessed it, and I got it on a short video clip. 61 00:05:09,000 --> 00:05:13,000 Nathan hasn't posted his video online. 62 00:05:13,000 --> 00:05:18,000 In fact, this is the first time he's agreed to show it to any outsider. 63 00:05:19,000 --> 00:05:28,000 At first, it doesn't look as if there's anything to see, but then, towards the top left of the frame, something strange appears. 64 00:05:28,000 --> 00:05:31,000 No, look right there. Look at that. Right there. 65 00:05:31,000 --> 00:05:32,000 See it? 66 00:05:32,000 --> 00:05:33,000 What is that? 67 00:05:33,000 --> 00:05:34,000 There is? 68 00:05:34,000 --> 00:05:35,000 What is it? 69 00:05:37,000 --> 00:05:42,000 It looks like a giant sea serpent, with three humps breaking the surface. 70 00:05:43,000 --> 00:05:52,000 If Nathan's right about the distance, that would make just the visible part of this lake creature, 40 to 50 feet long. 71 00:05:52,000 --> 00:05:53,000 Wow. 72 00:05:53,000 --> 00:05:55,000 That's cool. That's really cool. 73 00:05:55,000 --> 00:05:57,000 That's great. 74 00:05:57,000 --> 00:06:02,000 The quality is poor, so we're going to send off the video for some expert analysis. 75 00:06:05,000 --> 00:06:08,000 Shortly after, Nathan's right about the distance. 76 00:06:08,000 --> 00:06:09,000 Really? 77 00:06:11,000 --> 00:06:17,000 Shortly after this sighting, Nathan's friend, Fanyal, had a monster experience of his own. 78 00:06:17,000 --> 00:06:23,000 He's a fisherman, and was out in his canoe when the creature's surface just yards from him. 79 00:06:23,000 --> 00:06:25,000 What did it look like? 80 00:06:25,000 --> 00:06:28,000 Like a giant snake creature. 81 00:06:28,000 --> 00:06:29,000 Uh-huh. 82 00:06:29,000 --> 00:06:39,000 It's wide as the canoe, and three to four times longer than the canoe, and black, leathery-looking kind of skin. 83 00:06:39,000 --> 00:06:49,000 It had like that arch where, you know, it didn't just go straight, it actually had like a little arch with it or something. 84 00:06:49,000 --> 00:06:50,000 Like a jaw. 85 00:06:50,000 --> 00:06:52,000 Like this, now it came out. 86 00:06:52,000 --> 00:07:00,000 An arched neck means this was no giant fish, and it didn't move like a fish either. 87 00:07:00,000 --> 00:07:06,000 Where it has like the head, a hump, and a hump, it would do its, like it was like that. 88 00:07:06,000 --> 00:07:12,000 I was sitting there in awe, just dumbstruck of what I'm, what the heck am I looking at? 89 00:07:12,000 --> 00:07:21,000 Fanyal's description does seem to match the monster that Nathan caught on video, a giant serpent-like creature with humps. 90 00:07:22,000 --> 00:07:24,000 It's a lamp. 91 00:07:28,000 --> 00:07:35,000 And from the safety of the shore, Fanyal took his own video. 92 00:07:35,000 --> 00:07:41,000 He managed to capture this glimpse of the creature just before it disappeared under the surface. 93 00:07:41,000 --> 00:07:43,000 Yeah, what is that? 94 00:07:43,000 --> 00:07:58,000 It's only in modern times that people around the lake have had phones and cameras, but stories of the creature go way back. 95 00:07:58,000 --> 00:08:03,000 The native people of the area have lived here for nearly 10,000 years. 96 00:08:07,000 --> 00:08:11,000 For them, the story of the lake monster is no fairy tale. 97 00:08:13,000 --> 00:08:15,000 It's part of their oral history. 98 00:08:18,000 --> 00:08:21,000 Raymond Wassily is a native elder. 99 00:08:22,000 --> 00:08:41,000 I heard stories from all my elders before me of how they sought and stories are the ones that tell the truth for the nomads, because they didn't know how to write it. 100 00:08:43,000 --> 00:08:50,000 As a young man, Raymond himself had a close-up encounter with the monster when he was out on the lake with his family. 101 00:08:53,000 --> 00:08:59,000 My dad was on the cabin looking at it. He said it's longer than the boat. 102 00:08:59,000 --> 00:09:04,000 And the boat, the boat was almost like 32-footer end to end. 103 00:09:05,000 --> 00:09:09,000 It looked like it had a hump. 104 00:09:09,000 --> 00:09:18,000 And then I couldn't judge it, but it looked like it had three on the way back to it. 105 00:09:18,000 --> 00:09:22,000 Then it kind of sloped and it had a tail. 106 00:09:22,000 --> 00:09:28,000 And the head looked like it could swallow you. 107 00:09:28,000 --> 00:09:35,000 Three humps, just like in the video filmed by Nathan. 108 00:09:41,000 --> 00:09:46,000 Anthropologist Robin Levine is an expert on the native folklore. 109 00:09:46,000 --> 00:09:52,000 As an outsider, she was always skeptical about these stories of a lake monster. 110 00:09:52,000 --> 00:09:57,000 That is, until one July day back in 2008. 111 00:09:57,000 --> 00:10:03,000 A colleague of mine and I were flying back into a fish camp where we'd been conducting research. 112 00:10:03,000 --> 00:10:08,000 And we were on our way down, flying over a bay. We're very close to landing. 113 00:10:08,000 --> 00:10:12,000 And I saw something in the shallows, something I hadn't seen before. 114 00:10:12,000 --> 00:10:16,000 At first I thought it were two seals twisting together. 115 00:10:16,000 --> 00:10:20,000 And then I realized, no, it was one creature. 116 00:10:20,000 --> 00:10:24,000 Robin's first thought was a beluga whale. 117 00:10:24,000 --> 00:10:31,000 Belugas do swim in the waters of Alaska, and the size was about right. 118 00:10:31,000 --> 00:10:39,000 But belugas are almost white in color. The creature Robin saw was dark. 119 00:10:39,000 --> 00:10:46,000 It was pebble-colored. It had a simuous movement about it, but it was definitely not an eel. 120 00:10:46,000 --> 00:10:51,000 I could see pictorial fins. I could see tail fins. 121 00:10:51,000 --> 00:10:56,000 As soon as we landed and we were taxing up to the shore, I asked the pilot, 122 00:10:56,000 --> 00:10:59,000 well, what was that that we saw just in the bay as we were descending? 123 00:10:59,000 --> 00:11:04,000 And he got really excited. What did you see? What did you see? And I told him. 124 00:11:04,000 --> 00:11:08,000 And he said, congratulations. You've seen the Eleon the Lake Monster. 125 00:11:12,000 --> 00:11:17,000 I was really surprised, but it was at that time then that I recall the stories I'd heard, 126 00:11:17,000 --> 00:11:22,000 the stories that I dismissed years earlier about something in the water. 127 00:11:24,000 --> 00:11:31,000 Kiddu Viduak Lichard is a native shaman who was brought up on tales of the Lake Monster. 128 00:11:31,000 --> 00:11:35,000 So I've heard stories like this ever since I was little. My mom would tell me them. 129 00:11:35,000 --> 00:11:40,000 And I've heard similar stories from elders. I've heard these stories growing up my whole life. 130 00:11:40,000 --> 00:11:45,000 Nobody knows how old the stories are, but they go back hundreds, if not thousands of years 131 00:11:45,000 --> 00:11:50,000 before Western civilization arrived in America. These stories are not new. 132 00:11:52,000 --> 00:11:57,000 People have been living on Eleon the Lake for generation upon generation. 133 00:11:57,000 --> 00:12:00,000 The local people would say since time immemorial. 134 00:12:00,000 --> 00:12:06,000 And the way they pass on their knowledge, local knowledge, 135 00:12:06,000 --> 00:12:10,000 is from one generation to the next, from elders to their youth. 136 00:12:10,000 --> 00:12:16,000 And these stories help people survive. These stories help people develop a unique understanding 137 00:12:16,000 --> 00:12:19,000 of their landscape and their resources. 138 00:12:19,000 --> 00:12:26,000 This is where stories of the Eleon the Lake Monster have also come from. 139 00:12:26,000 --> 00:12:33,000 People, while they call it a monster, may be something that was picked up from the more recent 140 00:12:33,000 --> 00:12:38,000 Euro-Western visitors when they came and they heard some of these stories. 141 00:12:38,000 --> 00:12:45,000 But I imagine that the local people have stories about the Eleon the Lake Monster 142 00:12:45,000 --> 00:12:49,000 that helps them understand their natural environment. 143 00:12:51,000 --> 00:12:55,000 Since I was a baby, I've heard stories of these strange creatures. 144 00:12:55,000 --> 00:13:00,000 But instead of being thought of as fake or maybe they're real, 145 00:13:00,000 --> 00:13:04,000 Native Americans tend to take them very literally like we know they're real. 146 00:13:04,000 --> 00:13:07,000 They're just a part of life. They're a part of the world. 147 00:13:07,000 --> 00:13:11,000 Native communities accept it as part of reality. 148 00:13:11,000 --> 00:13:13,000 And that's how I grew up. 149 00:13:13,000 --> 00:13:17,000 I want our stories and our knowledge to be taken seriously. 150 00:13:19,000 --> 00:13:23,000 They go way further back than when Westerners came here. 151 00:13:23,000 --> 00:13:26,000 The Native people knew about them for a long time. 152 00:13:26,000 --> 00:13:28,000 And they weren't considered a mythology for the Native people. 153 00:13:28,000 --> 00:13:30,000 They're just considered a fact of life. 154 00:13:30,000 --> 00:13:33,000 You respect them. You don't mess with them because they're powerful. 155 00:13:33,000 --> 00:13:37,000 Come on, take our word for it. We've been here for a long, long time. 156 00:13:37,000 --> 00:13:39,000 We know what's in our own backyard. 157 00:13:41,000 --> 00:13:47,000 All over the Alaska Triangle, there's talk of undiscovered species and strange animals. 158 00:13:50,000 --> 00:13:56,000 The best known is the monstrous beast said to live in Lake Iliamna, the state's biggest lake. 159 00:13:57,000 --> 00:14:02,000 But the mystery surrounding this lake go beyond what lurks beneath. 160 00:14:04,000 --> 00:14:08,000 School teacher Sarah Armstrong lives overlooking the lake. 161 00:14:08,000 --> 00:14:15,000 But she grew up most in fear of Iliamna's bigfoot creature, what the locals call the hairy man. 162 00:14:16,000 --> 00:14:22,000 I remember growing up as a little girl, we would tease each other when we were out late at night. 163 00:14:23,000 --> 00:14:29,000 Watch out for the hairy man. And it would kind of give you this spooky feeling and the chills. 164 00:14:30,000 --> 00:14:34,000 But it was as an adult that Sarah had a first-hand experience. 165 00:14:35,000 --> 00:14:39,000 Myself and two of my friends, we were going on a camping trip. 166 00:14:40,000 --> 00:14:46,000 And Ray, who's up in the bow, says, what the hell is that? 167 00:14:47,000 --> 00:14:54,000 And we're all looking in this direction and our mind are just wondering what it is we're seeing 168 00:14:54,000 --> 00:14:56,000 and trying to focus your eyes. 169 00:14:58,000 --> 00:15:02,000 And within just a blink of an eye, it was gone. 170 00:15:03,000 --> 00:15:11,000 It just disappeared and we were just kind of in awe and stunned for a moment. 171 00:15:12,000 --> 00:15:18,000 And then we look at each other like, is that what we think we just saw? 172 00:15:19,000 --> 00:15:20,000 Did we just see this? 173 00:15:20,000 --> 00:15:26,000 It just looked like a tall black figure. 174 00:15:28,000 --> 00:15:41,000 I didn't really feel scared. I was just maybe more curious about the whole thing and kind of amazed at what we saw is what we saw. 175 00:15:42,000 --> 00:15:47,000 Something I've heard about my whole life I actually witnessed. 176 00:15:51,000 --> 00:16:02,000 There have been sightings of other strange cryptids around the lake too, including a bird the size of a small plane said to resemble a prehistoric pterodactyl. 177 00:16:04,000 --> 00:16:12,000 But the greatest is the lake-illumina creature. If it exists, it would dwarf anything in Alaska. 178 00:16:13,000 --> 00:16:22,000 In fact, there's only one obvious comparison, the most famous lake monster in the world, the Loch Ness Monster. 179 00:16:27,000 --> 00:16:32,000 Does Lake Illumina in Alaska really have its own prehistoric monster? 180 00:16:33,000 --> 00:16:43,000 Dr. Robert Alley is a retired professor from the University of Alaska and an expert cryptozoologist. 181 00:16:44,000 --> 00:16:51,000 Everyone's heard of the Loch Ness Monster. Well, it stands to reason if there could be a monster in the Loch Ness, there could be monsters elsewhere too. 182 00:16:52,000 --> 00:16:59,000 There's definitely something there. There have been photos, sonograms, pictures that have caused waves around the world. 183 00:17:03,000 --> 00:17:16,000 Many researchers have hypothesized that Loch Ness could hold a relic population of plesiosaur, that is extinct marine reptile. 184 00:17:17,000 --> 00:17:25,000 The head of a plesiosaur would be an exact match for the monster spotted by Fanyal Kiesling when he was out in his canoe. 185 00:17:26,000 --> 00:17:28,000 It had like an arch, like a jaw. 186 00:17:28,000 --> 00:17:30,000 It was like the snout came out. 187 00:17:32,000 --> 00:17:36,000 And it's a good match for the traditional image of the Loch Ness Monster. 188 00:17:39,000 --> 00:17:50,000 And this Loch Ness photo from the 50s seems to show a huge water creature with humps, just like the monster seen by Nathan Hill. 189 00:17:51,000 --> 00:18:01,000 Every year, a million people visit Loch Ness in the hope of catching a glimpse of the mysterious beast. 190 00:18:02,000 --> 00:18:07,000 Compared to Loch Ness, Lake Iliamna is remote and isolated. 191 00:18:08,000 --> 00:18:13,000 Few tourists come here and only about 600 people live on its shores. 192 00:18:14,000 --> 00:18:18,000 The lake is also over 50 times bigger than Loch Ness. 193 00:18:19,000 --> 00:18:24,000 If finding the Loch Ness Monster is difficult, then what are the chances here? 194 00:18:26,000 --> 00:18:30,000 There's one man who thinks the monster may already have been found. 195 00:18:31,000 --> 00:18:39,000 We got a quick giveaway here. This Memorial Day weekend, Americans will take time to remember and honor those who died while serving our country. 196 00:18:39,000 --> 00:18:50,000 Local radio DJ Bob Bird has unearthed evidence that back in 1967, the monster of Lake Iliamna was not only found, but caught. 197 00:18:51,000 --> 00:18:59,000 In a plane like this, Chuck Crappershott, who was a missionary, Christian missionary, spotted from the air and radioed some friends. 198 00:19:00,000 --> 00:19:03,000 I've got this large fish swimming right underneath the surface. 199 00:19:04,000 --> 00:19:13,000 Word quickly spread around the airwaves that this could be the lake monster, and the idea was mooted to try to catch it. 200 00:19:15,000 --> 00:19:32,000 Somebody, with a sense of adventure, took a float plane, put on some probably very strong halibut line with large hooks, and cinching them to a cleat like that, tossed the meat into the water. 201 00:19:33,000 --> 00:19:41,000 Well, as he lollygagged on the floats itself, well, before too long his plane was being towed around. 202 00:19:43,000 --> 00:19:50,000 Beneath the surface, some giant creature with immense strength was pulling the plane across the water. 203 00:19:51,000 --> 00:20:01,000 Eventually, the monster broke free. On inspecting the damage, it was clear that it was well beyond the capabilities of any known lake creature. 204 00:20:03,000 --> 00:20:12,000 His plane was towed around. He looked at the hooks. They'd been straightened out, and maybe others had been bitten off. 205 00:20:13,000 --> 00:20:21,000 It would take unbelievable strength to straighten out the large tuna hooks and bite through the thick, stainless steel cables. 206 00:20:22,000 --> 00:20:27,000 The creature would have to be gigantic, as big as a dinosaur, perhaps. 207 00:20:28,000 --> 00:20:36,000 If we're talking about a plesisaur, a creature like this would absolutely have no problem towing a plane around on the surface of the lake. 208 00:20:36,000 --> 00:20:43,000 These creatures were huge, up to 50 feet. To them, a float plane on the surface of the lake would be like a toy. 209 00:20:45,000 --> 00:20:55,000 If there is a giant dinosaur-like creature hiding in the lake, then cryptozoologist Cliff Berwickman is determined to find it. 210 00:20:55,000 --> 00:21:00,000 He's decided to put all his trust in local fisherman Richard Walton. 211 00:21:05,000 --> 00:21:10,000 Thank you for letting me on your boat and showing me around a little bit. Safe to say, you know this lake pretty well. 212 00:21:10,000 --> 00:21:16,000 We've traveled this lake quite a bit over the course of a lifetime, you know, because it's kind of what you do here. 213 00:21:16,000 --> 00:21:20,000 This is your road system. This is how you get around all the different communities. 214 00:21:21,000 --> 00:21:30,000 Like Loch Ness, Lake Iliamna is exceptionally deep, and what lies beneath the surface is largely unexplored. 215 00:21:30,000 --> 00:21:35,000 There's anywhere a lake monster can lie hidden in the depths. It's here. 216 00:21:37,000 --> 00:21:42,000 But for Cliff, comparisons with Loch Ness go deeper than you might think. 217 00:21:43,000 --> 00:21:50,000 All throughout British Columbia and Alaska, there are literally hundreds of lakes that have reported lake monsters living in them. 218 00:21:50,000 --> 00:21:59,000 And what I find interesting about that is that the latitude is very similar to that of Scotland, where the Loch Ness monster is. 219 00:22:00,000 --> 00:22:05,000 Similarities of climate and water temperature may partially account for this. 220 00:22:05,000 --> 00:22:13,000 And in these colder parts, it's easier for creatures to remain hidden, as there's more wilderness and fewer people. 221 00:22:19,000 --> 00:22:24,000 But there are times when something strange is spotted, even in a populated area. 222 00:22:36,000 --> 00:22:51,000 In the Alaska Triangle, it's not inconceivable that strange, unknown creatures could be hiding in the forests or lurking in its waters. 223 00:22:53,000 --> 00:22:56,000 Even large new animals are still being discovered. 224 00:22:57,000 --> 00:23:06,000 In June 2016, this 24-foot whale washed up in Alaska and was found to be an entirely new species. 225 00:23:10,000 --> 00:23:20,000 Now, journalist and researcher Andrew Goff has pinpointed the Alaska Triangle as being ripe for new discoveries of river and lake creatures. 226 00:23:21,000 --> 00:23:27,000 It's really a perfect storm, a remote location with huge bodies of water. 227 00:23:28,000 --> 00:23:34,000 It's full of species that we've yet to identify or even begun to understand. 228 00:23:34,000 --> 00:23:37,000 So the natural reaction is to call them monsters. 229 00:23:37,000 --> 00:23:41,000 You can understand that, but really, they're just new species. 230 00:23:41,000 --> 00:23:45,000 And they probably have been here even longer than we have. 231 00:23:46,000 --> 00:23:52,000 It's the ideal spot for species to go unnoticed for hundreds of years. 232 00:23:55,000 --> 00:24:00,000 In November 2016, there was a sighting that created an online storm. 233 00:24:01,000 --> 00:24:06,000 This video appeared linked to the Alaska Bureau of Land Management. 234 00:24:07,000 --> 00:24:11,000 Within days, it racked up over a million views. 235 00:24:16,000 --> 00:24:24,000 The location? The China River Fairbanks, right in the middle of the Alaska Triangle. 236 00:24:26,000 --> 00:24:31,000 Where government worker and keen photographer Craig McCaw happens to be based. 237 00:24:33,000 --> 00:24:38,000 He was out on a routine job inspecting the river from this bridge. 238 00:24:39,000 --> 00:24:43,000 I was walking out on the bridge that you can see behind me there 239 00:24:43,000 --> 00:24:47,000 and taking some photos of ice beginning to form. 240 00:24:47,000 --> 00:24:50,000 This was in late October, which is early winter in Fairbanks, 241 00:24:50,000 --> 00:24:53,000 and took out my camera, pointed at this direction, 242 00:24:53,000 --> 00:24:58,000 and my attention was caught by movement in the river right beneath me. 243 00:24:59,000 --> 00:25:02,000 I looked down in the water and I did a total stop. 244 00:25:02,000 --> 00:25:06,000 When Craig looked down, he saw something extraordinary. 245 00:25:06,000 --> 00:25:11,000 So he got out his phone and took this video. 246 00:25:16,000 --> 00:25:22,000 Right below him was what looked like a giant serpent-like ice monster, 247 00:25:22,000 --> 00:25:26,000 strong enough to be swimming upstream in the fast-flowing current. 248 00:25:26,000 --> 00:25:33,000 So I'm looking at it now, right in the river, right over there. 249 00:25:33,000 --> 00:25:39,000 It's a little strange to see this thing swirling back and forth in the river. 250 00:25:39,000 --> 00:25:44,000 It's got a rough texture. You can see that it has ice on it, 251 00:25:44,000 --> 00:25:48,000 and a lot of the rest of it is obscured by the murky water. 252 00:25:49,000 --> 00:25:56,000 Close analysis of the video puts this strange creature at about 20 feet long, 253 00:25:56,000 --> 00:25:59,000 but that's just the visible part. 254 00:25:59,000 --> 00:26:05,000 There's no known animal in this river with the size anything like that. 255 00:26:07,000 --> 00:26:11,000 Send this shiver down my spine. I'd never seen anything like that. 256 00:26:12,000 --> 00:26:17,000 Is this an unknown species or a relic from prehistory? 257 00:26:25,000 --> 00:26:30,000 It's certainly true that prehistoric creatures do exist in these waters. 258 00:26:32,000 --> 00:26:35,000 These blood-sucking fish, known as lampreys, 259 00:26:35,000 --> 00:26:39,000 were around 200 million years before the dinosaurs. 260 00:26:41,000 --> 00:26:48,000 And they can still be found in Alaska, even here, in the middle of Fairbanks. 261 00:26:48,000 --> 00:26:56,000 In fact, in June 2015, bizarrely, they began falling onto the streets of the city. 262 00:26:57,000 --> 00:27:03,000 Fish literally started raining from the sky. How on earth does that happen? 263 00:27:04,000 --> 00:27:11,000 In Cardiff, in the United Kingdom, Dr. Rhys Jones is a senior lecturer in biosciences 264 00:27:11,000 --> 00:27:13,000 and an environmental researcher. 265 00:27:14,000 --> 00:27:19,000 When I say fish, I mean fish like this one here. This is a lamprey. 266 00:27:19,000 --> 00:27:22,000 Superficially, it looks a little bit like an eel, 267 00:27:22,000 --> 00:27:27,000 but actually, if I turn it around, have a look at the face on there. 268 00:27:28,000 --> 00:27:36,000 These are sharp tooth, foot-long, blood-sucking eel-like fishes. 269 00:27:36,000 --> 00:27:44,000 These are vampire fishes that attach themselves to other animals and suck their blood. 270 00:27:44,000 --> 00:27:47,000 Now, they're rarely seen, let alone caught, 271 00:27:47,000 --> 00:27:54,000 but here they are falling from the sky miles from any river. 272 00:27:54,000 --> 00:27:56,000 How can that be? 273 00:27:57,000 --> 00:28:01,000 It's hard to imagine what these ordinary people would have thought. 274 00:28:02,000 --> 00:28:07,000 They must have been terrified, mystified, and utterly freaked out. 275 00:28:08,000 --> 00:28:13,000 How the lamprey came to be falling from the sky has never been established. 276 00:28:14,000 --> 00:28:21,000 But could the serpent-like ice creature be a kind of giant prehistoric blood-sucking fish? 277 00:28:21,000 --> 00:28:28,000 When I started filming this object in the river, I didn't really know. 278 00:28:28,000 --> 00:28:30,000 I still don't know what it was. 279 00:28:32,000 --> 00:28:36,000 It moved like a giant fish. I have to say that the way it undulated in the current, 280 00:28:36,000 --> 00:28:38,000 and it kind of held its place. 281 00:28:41,000 --> 00:28:46,000 Generally speaking, what's in the Chino River is some species of freshwater fish, 282 00:28:46,000 --> 00:28:49,000 like Arctic graling, north of the Chino River. 283 00:28:49,000 --> 00:28:56,000 There's some mammals that pass through the river or a beaver that live in and around the river. 284 00:28:56,000 --> 00:29:00,000 But I can't think of anything that's more than three or four feet long, 285 00:29:00,000 --> 00:29:03,000 and what I saw was much, much larger than that. 286 00:29:05,000 --> 00:29:09,000 Nature still provides these mysteries from time to time that force you to stop 287 00:29:09,000 --> 00:29:13,000 and think, what am I looking at? How can I explain this? 288 00:29:14,000 --> 00:29:21,000 Whether a strange giant fish or not, could this creature be related to the monster of Lake Iliamna? 289 00:29:24,000 --> 00:29:28,000 The Chino River is a tributary to the mighty Yukon River, 290 00:29:28,000 --> 00:29:33,000 which connects many of the waterways and lakes of Alaska to the coast. 291 00:29:33,000 --> 00:29:37,000 And then from there, it's a short journey upriver to Lake Iliamna. 292 00:29:37,000 --> 00:29:42,000 This means that there's a ready network for these creatures to disperse throughout the triangle. 293 00:29:44,000 --> 00:29:48,000 But is there any evidence of more than one lake monster? 294 00:29:51,000 --> 00:29:55,000 The local radio station has been taking calls on the subject. 295 00:29:59,000 --> 00:30:02,000 Welcome back to the Birds Eye View on Lake Iliamna. 296 00:30:02,000 --> 00:30:06,000 Welcome back to the Birds Eye View on KSRM. 297 00:30:10,000 --> 00:30:11,000 Uh, Celtic. 298 00:30:11,000 --> 00:30:17,000 DJ Bob Bird has had one call that suggests the Lake Iliamna creature is not alone. 299 00:30:17,000 --> 00:30:20,000 We saw three, 300 00:30:20,000 --> 00:30:24,000 identical creatures. 301 00:30:24,000 --> 00:30:29,000 And these things were just, absolutely, he was going to have no idea what they could have been. 302 00:30:29,000 --> 00:30:32,000 Rounded, slightly rounded, 303 00:30:32,000 --> 00:30:37,000 long, darkish, blackish gray, 304 00:30:37,000 --> 00:30:40,000 is well over 60 feet. 305 00:30:41,000 --> 00:30:46,000 Increasingly, the calls to Bob's show aren't just about Lake Iliamna. 306 00:30:46,000 --> 00:30:52,000 Bob's many listeners have added to the evidence of monsters elsewhere in the region too. 307 00:30:53,000 --> 00:30:57,000 There's also similar sightings in other large lakes. 308 00:30:57,000 --> 00:31:02,000 Lake Clark, which feeds into Lake Iliamna, has its own legends. 309 00:31:02,000 --> 00:31:07,000 Basharov Lake, which is south of Iliamna, had a very credible sighting. 310 00:31:08,000 --> 00:31:12,000 Bob's now convinced that witnesses to the monster are genuine. 311 00:31:13,000 --> 00:31:17,000 We're not dealing with a mirage, a deluded individual. 312 00:31:17,000 --> 00:31:20,000 We're not dealing with mistaken identities. 313 00:31:21,000 --> 00:31:24,000 We've got something that needs explaining. 314 00:31:27,000 --> 00:31:34,000 Bob's own investigations have led him to what could be a secret government report on these lake monsters. 315 00:31:35,000 --> 00:31:41,000 As I understand it, the Alaska Department of Fish and Game kept once a file on the sightings 316 00:31:41,000 --> 00:31:44,000 to see what sort of consistency there might be in the reports. 317 00:31:45,000 --> 00:31:49,000 I don't know if that file exists anymore because as a journalist, two years ago, 318 00:31:49,000 --> 00:31:53,000 I asked them to find it for me and they didn't have it. 319 00:31:53,000 --> 00:31:56,000 I have no doubt there was once a file. 320 00:31:57,000 --> 00:32:00,000 What was in that file? We don't know. 321 00:32:00,000 --> 00:32:05,000 But the caller to Bob's show has agreed to tell his story on camera. 322 00:32:06,000 --> 00:32:10,000 These things were awful big and there was a lot of them. 323 00:32:10,000 --> 00:32:18,000 One clear afternoon in the late 90s, local businessman Gary Nielsen was out on the lake with his wife. 324 00:32:19,000 --> 00:32:27,000 My wife was looking over the side and she screams and she's on my side of the boat in my lap 325 00:32:27,000 --> 00:32:34,000 screaming at me to go faster so I just automatically hit the throttle fast forward. 326 00:32:34,000 --> 00:32:38,000 And as I looked back to where she was looking, there was these two heads. 327 00:32:38,000 --> 00:32:43,000 Probably about that long and about that wide and I was just the heads. 328 00:32:43,000 --> 00:32:47,000 And they were traveling like that and they were looking at us as we were going by. 329 00:32:49,000 --> 00:32:56,000 The heads were maybe two feet long, maybe longer, 16 to 18 inches wide. 330 00:32:57,000 --> 00:33:03,000 Triangular shaped, very sleek looking and the bodies were awful long 331 00:33:03,000 --> 00:33:07,000 but I couldn't tell the body length because I was too busy trying to get into the shallow water. 332 00:33:07,000 --> 00:33:09,000 These things were big. 333 00:33:10,000 --> 00:33:17,000 Gary's detailed description matches that of other witnesses and also that of the Loch Ness monster. 334 00:33:18,000 --> 00:33:22,000 For the scientists, multiple monsters is a given. 335 00:33:23,000 --> 00:33:26,000 If there's one monster, there has to be more than one. 336 00:33:26,000 --> 00:33:30,000 There has to be a breeding population. There can never be just one. 337 00:33:30,000 --> 00:33:37,000 When you have a biological population, you've got to have significant numbers for maintaining a gene pool. 338 00:33:38,000 --> 00:33:44,000 There's one particular aspect of the lake creatures that haunts Gary to this day. 339 00:33:44,000 --> 00:33:46,000 The eyes were so huge. 340 00:33:47,000 --> 00:33:50,000 They were just big, round. 341 00:33:51,000 --> 00:33:54,000 The best description is dead black eyes. 342 00:33:55,000 --> 00:34:00,000 Like they were made for deep water where there's less light. 343 00:34:01,000 --> 00:34:08,000 Huge eyes made for deep water could be a clue to how these monsters are connected to the triangle. 344 00:34:09,000 --> 00:34:16,000 There's an old native belief that the separate waterways and lakes are linked by underground channels. 345 00:34:19,000 --> 00:34:24,000 It's a story that Robin Levine has come across as a part of her work with the native people. 346 00:34:26,000 --> 00:34:35,000 One of the stories I heard when I was out there was that there's a possibility that the elders say that there may be an underwater passage, 347 00:34:35,000 --> 00:34:41,000 a tunnel from Iliumna Lake to the saltwater inlet. 348 00:34:43,000 --> 00:34:46,000 Could it really be possible that these links exist? 349 00:34:48,000 --> 00:34:51,000 Well, there's some firm science that suggests they do. 350 00:34:52,000 --> 00:35:00,000 And with access to the sea through large underwater passageways, any number of giant creatures could be in there. 351 00:35:06,000 --> 00:35:14,000 Bruce Wright is a former professor from the University of Alaska, and he's been researching the bed of the lake. 352 00:35:15,000 --> 00:35:25,000 It's so deep. It's at least 1200 feet, but nobody knows. Nobody's taken a rock tied to a string and dropped it down to the bottom. 353 00:35:27,000 --> 00:35:33,000 As well as being of unknown depth, the lake lies on top of unstable bedrock. 354 00:35:35,000 --> 00:35:40,000 It's a geologically active area. There probably are cracks down at the bottom of the lake. 355 00:35:41,000 --> 00:35:45,000 Kind of makes you wonder, well, maybe there's a link to the ocean through these things. 356 00:35:47,000 --> 00:35:53,000 From the coast, any number of creatures could navigate their way up into Lake Iliumna. 357 00:35:57,000 --> 00:36:03,000 For Gary Nielsen and his wife, spotting two lake monsters was just the start. 358 00:36:03,000 --> 00:36:09,000 As I was watching them, I saw all these other wakes all around and up in front. 359 00:36:10,000 --> 00:36:13,000 And some of the ripples were, or wakes, were like two feet high. 360 00:36:14,000 --> 00:36:21,000 Multiple wakes two feet high, they could only be caused by something massive moving in the water. 361 00:36:22,000 --> 00:36:28,000 We didn't bother to go out and try to see how big those big ones were, because we were busy trying to stay alive in shallow water. 362 00:36:28,000 --> 00:36:33,000 They wouldn't go in the shallow water for whatever reason. 363 00:36:34,000 --> 00:36:39,000 When I say shallow, my skiff draws about 14 inches with the motor down. 364 00:36:40,000 --> 00:36:43,000 I had my motor jilted up to stay in the shallow water, so I was probably in the flipperless water. 365 00:36:44,000 --> 00:36:48,000 I mean, I was literally scraping over the rocks where the seals were. 366 00:36:49,000 --> 00:36:55,000 And I didn't care if I'd dinged up my prop or anything, because I just did not want to be out there in the deep water with whatever the hell those things were. 367 00:36:55,000 --> 00:36:57,000 I neither did the seals. 368 00:36:58,000 --> 00:37:01,000 I had my rifles, I had two rifles, a .22 and a .06. 369 00:37:02,000 --> 00:37:06,000 And I could have got everyone on those seals if I wanted to, but I had no interest in the seals at that time. 370 00:37:07,000 --> 00:37:08,000 I just wanted to stay away from those creatures. 371 00:37:09,000 --> 00:37:14,000 I go into the shallow water just enough for my, so my kicker doesn't hit. 372 00:37:15,000 --> 00:37:18,000 Trying to avoid these fish. 373 00:37:19,000 --> 00:37:23,000 There's a little island there, and it's full of rocks. 374 00:37:24,000 --> 00:37:30,000 There's got to be a hundred seals up on the rocks, just to scare them off of us or whatever it was in the water. 375 00:37:31,000 --> 00:37:32,000 They would not go in the water. 376 00:37:33,000 --> 00:37:36,000 Their rivers, we could have reached out and touched them, because they would not go in the water. 377 00:37:37,000 --> 00:37:42,000 If they went and they come right back out on the rocks, because these fish were out there circling, just waiting for them to get into the water. 378 00:37:43,000 --> 00:37:48,000 And we were there by the island, and we couldn't stay there. 379 00:37:48,000 --> 00:37:52,000 There were these wakes between us and the mainland. 380 00:37:53,000 --> 00:37:54,000 So we waited until the wakes went by. 381 00:37:55,000 --> 00:37:59,000 We went into the mainland, into the shallow water, followed the beach for about three miles. 382 00:38:00,000 --> 00:38:02,000 There were no more wakes. We went to Pal Bay. 383 00:38:03,000 --> 00:38:06,000 But that's the scariest I've ever been when I saw something in the water. 384 00:38:07,000 --> 00:38:08,000 I don't really get scared. 385 00:38:09,000 --> 00:38:13,000 I crawl into a brush after a wounded animal, big wounded animal like bears and moose that are not happy. 386 00:38:14,000 --> 00:38:15,000 That's a different kind of fear. 387 00:38:15,000 --> 00:38:17,000 You know, you're scared, but you're aware, you're hunting. 388 00:38:18,000 --> 00:38:22,000 This was a different kind of fear. It was like, I can get the hell out of here kind of fear. 389 00:38:23,000 --> 00:38:24,000 You don't want to be here kind of fear. 390 00:38:25,000 --> 00:38:27,000 It wouldn't take much for them to use to jump up near us. 391 00:38:28,000 --> 00:38:29,000 They were that big. 392 00:38:30,000 --> 00:38:38,000 I'd been in extremely rough weather and a sinking skiff, where everything I had in the skiff washed overboard, except for me and the tank that my kicker was connected to. 393 00:38:39,000 --> 00:38:41,000 I'd been after wounded animals. 394 00:38:42,000 --> 00:38:44,000 They knew would probably kill me if they had a chance. 395 00:38:45,000 --> 00:38:47,000 I was scared, but I'm not that kind of scared. 396 00:38:50,000 --> 00:38:53,000 But there's another scientific question that needs answering. 397 00:38:54,000 --> 00:39:00,000 If the lake has a large population of giant prehistoric beasts, what are they feeding on? 398 00:39:01,000 --> 00:39:02,000 How are they surviving? 399 00:39:04,000 --> 00:39:06,000 The answer lies in the water. 400 00:39:06,000 --> 00:39:10,000 The answer lies in Alaska's abundant wildlife. 401 00:39:13,000 --> 00:39:18,000 Alaska has a really wide variety of marine animals because it's so productive up here. 402 00:39:19,000 --> 00:39:26,000 A lot of that's driven by the cleanliness of the waters off of Alaska, but also there's high oxygen levels. 403 00:39:27,000 --> 00:39:35,000 So we have good phytoplankton bloom and that energy drives this really rich, valuable set of organisms that live up here. 404 00:39:36,000 --> 00:39:37,000 And lots of fish. 405 00:39:38,000 --> 00:39:43,000 If a large unknown species was to exist anywhere, this would be the place. 406 00:39:44,000 --> 00:39:45,000 Food is plentiful. 407 00:39:47,000 --> 00:39:52,000 And one fish in particular provides a direct link to Loch Ness in Scotland. 408 00:39:54,000 --> 00:40:00,000 There's five million salmon that are entering this big lake, moving up into the rivers or spawning right along the shoreline. 409 00:40:01,000 --> 00:40:05,000 And the salmon really drive the terrestrial ecosystem. 410 00:40:06,000 --> 00:40:14,000 The energy from the salmon moves through the ecosystem via bears and eagles that eat the salmon and move those nutrients up into the ecosystem. 411 00:40:15,000 --> 00:40:24,000 In fact, if you go out and you look at the stable isotopes of certain atoms in the trees, you'll find out that they're mostly made of salmon. 412 00:40:25,000 --> 00:40:38,000 Like Loch Ness, because of the salmon, Lake Iliamna could sustain any number of fish eating plesiosaurus and multiple monsters would increase the danger out on the lake. 413 00:40:42,000 --> 00:40:46,000 It's a theory that Gary now holds to because of his own encounter. 414 00:40:47,000 --> 00:40:54,000 And there's old stories about that that I never ever believed from way back when of them pulling people out of kayaks or boats even. 415 00:40:54,000 --> 00:40:56,000 I never believed until that moment. 416 00:41:01,000 --> 00:41:08,000 Out on the lake, cryptozoologist Cliff Berwickman is determined to investigate what's going on beneath the surface. 417 00:41:09,000 --> 00:41:14,000 If there was just one lake creature, it could be anywhere. 418 00:41:16,000 --> 00:41:21,000 But multiple creatures would significantly increase his chance of seeing something. 419 00:41:21,000 --> 00:41:26,000 And the boat's sonar can detect anything big moving beneath them. 420 00:41:27,000 --> 00:41:35,000 A lot of fishermen rely on tools like this, you know, for their livelihood, you know, to find big schools of fish for the same nets and all that stuff. 421 00:41:36,000 --> 00:41:47,000 But this would also be a very effective tool to see any large animal under the surface too, not just smaller fish, but like something large like one of these lake creatures. 422 00:41:57,000 --> 00:42:03,000 Mysterious shapes pass by beneath them, but it's impossible to identify what they are. 423 00:42:05,000 --> 00:42:10,000 Is this a plesiosaur? Head up, swimming deep beneath them. 424 00:42:10,000 --> 00:42:13,000 It's something moving across the screen. 425 00:42:13,000 --> 00:42:15,000 That's a big one, whatever it is. 426 00:42:16,000 --> 00:42:22,000 The best image Cliff has is the video taken by Nathan Hill, the local borough manager. 427 00:42:23,000 --> 00:42:28,000 It's this video we're keen to have analyzed, and we're showing it to Dr. Alley. 428 00:42:29,000 --> 00:42:43,000 I'm looking here at a video of Lake Ilieumid, and we can actually see three objects above the water that appear to be curved and not linear like a wave would be. 429 00:42:43,000 --> 00:42:57,000 So it's suggestive of a biological creature, and in fact, if you had to compare it with something, with any one thing, you'd want to compare it with those three hump little statues that you see in the water. 430 00:42:58,000 --> 00:43:04,000 There's a picture of them in the gift shops at Loch Ness showing head, middle, bump, one, two, three. 431 00:43:04,000 --> 00:43:11,000 And you know you don't have schools of porpoise jumping in Lake Ilieumid, and a stelfel of three sturgeon are going to arise. 432 00:43:11,000 --> 00:43:21,000 What this suggests is something that's swimming in the manner, not of a reptile or a fish with a lateral undulation or amphibian, but rather a mammal. 433 00:43:21,000 --> 00:43:24,000 This is a tremendously exciting thing to watch. 434 00:43:25,000 --> 00:43:35,000 Possibly unidentified species or fossil mammals that we think are extinct may actually still be living trapped in fresh water. 435 00:43:35,000 --> 00:43:42,000 It would suggest just as equally aplesiast are. So there are those who say it's a mammal, there are those who say it's no, it's got to be a reptile. 436 00:43:42,000 --> 00:43:47,000 We know it's got to be something, something's in there, but what is it? 437 00:43:48,000 --> 00:43:55,000 Out on the lake, Cliff and Richard find no conclusive evidence. 438 00:43:55,000 --> 00:44:01,000 Considering the size of the task in hand, this is no great surprise. 439 00:44:01,000 --> 00:44:10,000 According to scientists, even with a large number of lake monsters, sightings could still remain very rare. 440 00:44:11,000 --> 00:44:27,000 If you have salty water at the bottom of the lake that is oxygenated by some geological phenomena, you could have some really unusual animals living down there that could stay down there, be inactive. 441 00:44:27,000 --> 00:44:33,000 And then when the salmon show up, go eat your 5,000 pounds of salmon and then just go back down there. 442 00:44:33,000 --> 00:44:40,000 For those who've seen the monster, an unknown species certainly fits the bill. 443 00:44:40,000 --> 00:44:48,000 It's easy to dismiss what we call myths, what we call legends, until you've actually witnessed it yourself. 444 00:44:48,000 --> 00:44:57,000 And then you realize that what people might refer to as a myth, what people might refer to as a legend, is actually local knowledge. 445 00:44:58,000 --> 00:45:08,000 What I saw was perhaps its own unique type of species, as yet undiscovered. 446 00:45:12,000 --> 00:45:20,000 At first I wasn't convinced. I'm pretty skeptical scientists. I like to hold in my hand what we're talking about. 447 00:45:20,000 --> 00:45:27,000 But it's hard to talk to anybody out there that hasn't interacted with this animal or seen it. 448 00:45:27,000 --> 00:45:32,000 You talk to all these people and it's just convincing there's something out there. 449 00:45:35,000 --> 00:45:41,000 We have so many more questions to answer. And that's the wonder of Alaska. 450 00:45:43,000 --> 00:45:48,000 Be aware. A lot of things can kill you out here without even trying.
