Vasquez Rocks Natural Area is a 932 acre park outside of Santa Clarita in the Sierra Pelona Mountains. Located along the San Andreas Fault, these sandstone rocks were formed 25 million years ago. Tataviam Native Americans lived in grass hut villages here and considered the site sacred. The rocks were named for Tiburcio Vasquez, a notorious bandit who used the area as a hideout in 1874. Hollywood has filmed here since the 30's including The Flintstones, Star Trek and Planet of the Apes.
