There was a natural cave up there that only went back far enough to make it look like a cave. There's also a few prospect mines in that area. One is covered with bars. The other two only went back maybe five feet.
There is nothing up there that even resembles a motor or plane part that we saw. There may still be parts up there, but they'd be scattered. From what I read, the largest parts; fuselage, wings, landing gear were collected not long after the crash. There were smaller parts of the motors left, but those seem to be gone now too.
We did see a few large pieces of unidentifiable parts near the base. We figured they just fell after the crash.
