The photograph shown above is from the 1951 movie Jungle Manhunt, starring Johnny Weissmuller, Sheila Ryan, Bob Waterfield (a popular quarterback from the Los Angeles Rams), Rick Vallin and Lyle Talbot.

The Trail Blazer Cave The cave was a clever fake. The right side had been built up with plaster and cement. Shown at the cave's front entrance are from left to right: Bob Steele, Hoot Gibson, and Ken Maynard. 

Movies that used this location include Arizona Whirlwind, Billy the Kid vs. Dracula, The Range Busters, The Fugitive with David Janson (episode 10,000 Pieces of Silver), and Nyoka and the Tigermen (this 14-chapter serial used the back entrance of the cave)

Caves (Rock Shelter) The Chumash Indians lived in these caves and rock shelters for hundreds of years. Due to local weather conditions, most of the Indians' shelters faced east and south. The Chumash used caves in this area as stopping places as they travelled through the region. These are natural formations in the sandstone.

Lichen Notice the tri-colored plants growing on the sandstone rocks. This plant, called lichen, is composed of both algae and fungus growing as a single unit. The algae produce food and the fungus holds onto the rock. This is a good example of the symbiotic relationship in which one plant cannot live without the other. "Algae and fungus took a lichen to each other, but the marriage ended up on the rocks." They also break down the rock and provide soil for future plants to grow.

Sandstone Rocks Large sandstone rock formations are located throughout the park. Sandstone is a sedimentary rock that was formed at the bottom of the ocean floor from compressed sand. Thick desposits of sandstone built up under the ocean over millions of years to form the cliffs that you see. Over time, the rocks were exposed to the weather through upheaval and continental plate movement.
