Pinnacles National Park is one half of an ancient volcano that was cut into two by tectonic forces about 20 million years ago. Two thirds of the volcano eventually became Pinnacles National Park while the other side of it became the Neenach Formation almost 200 miles south. Our visit this time had us explore Bear Gulch talus caves. Talus caves are caves formed by boulders and rocks that fall into a narrow canyon. The canyons here are the result of faults and fractures in the central area of volcanic rock. Rock falls that helped form Bear Gulch Caves are believed to have occurred during the last Ice Age.
