I must be crazy but......
I have seen the same big rock (mountain) in quite a few movies and TV shows. Some of the movies go back 50 years. I have seen it on Star Trek TNG and most recently NCIS-South by Southwest. It seems that when ever a a desert scene is required this rock has to be in the scene.
Large gray mountain.
Sticking out of the ground at about a 50 degree angle.
Very sharp and weathered.
I just wondered where it was (back lot of a studio?) and if it had a name?
