Still, geologists kept finding stubborn little problems with the assumption of vertical motion. Levi Noble suggested in 1927 that the fault in southern California had shifted some Cenozoic sediments around 26 miles. The idea was controversial. Robert Wallace produced even more debate, suggesting in his Ph.D. thesis that a portion of the fault in the Mojave Desert had been shifted 75 miles sideways.

There are miles of other trails in the park, including the High Peaks Trail that must not be missed as long as your phobia of heights is held in check. It is a marvelous 5 mile loop that provides awesome views. Other trails explore the sycamore woodlands along the streams. There are several visitor centers and a campground. If you pay close attention, you will see California Condors soaring in the skies above.
