Found it! Here:http://www.dukewayne.com/showthread/php?t=2528http://www.dukewayne.com
scroll down to the bottom and see the rock formation and what shows it was featured on but no mention of Short Circuit it figures!
OK the link doesn't seem to work but the name is called:
Vasquez Rocks Natural Area Park
Agua Dulce California
I googled it under images and found the picture and clicked and it took me to that site what I typed in was "Famous Rocks used in Movies and TV Shows"
