Whats the classified airfield on the north end of NTS Area 20 at 
37�22'12.42"N 116�49'39.74"W (E,NE of Scotty's Junction) ?

There are no FAA, DoD, DoE, or EPA references to it but it has a 7,200 foot 
runway.

It's just south of the bombing ranges and has a paved road leading up to an 
observation point on the peak.
