I haven't been to the range 61 gate in years. They used to have a
repeater of sorts there, but it was removed. Anyway, here is a photo
of a camera at the gate. Now this area is very remote, so how this
camera is powered is a subject of debate. The photos don't show a
solar array, so again, my guess is a big ass gel cell. Now I suppose
the camera could be there in anticipation of the new power lines going
through the area.
