Fluxlib - interesting. "Airplane Gully" is a little south of there, on the north side of Niwot Ridge near Navajo Pk. There's a tremendous amount of airplane debris there. Very spooky to hike up the gully by moonlight with a breeze making the metal flap.
Wilson Peak in CO also had a plane crash on the summit in the past few years. The last time I was up there, there was not just plane debris, but shredded clothing and personal items lying around on the way up the summit. At the top, a little monument had been started with people placing the objects in a pile. It's a strange feeling.
