THe distant peak in the top left is Mount Charleston and this was the scene of a secret military C54 crash in 1955. It was secret as occupants on board were all working on the U2 program. Apparently the plane missed clearing the summit by about 50 feet in bad weather, 14 people died. The plane was pretty intact and was blown up by the military to destroy any evidence apparently many parts are still scattered around up there. The details were recently made public after 40 years had passed.
