Spelunking for Glyphs at Lava Beds National Monument in Tulelake, CA
Although experienced “cavers” collecting scientific data don bump hats, kneepads, and carry fancy equipment, amateur spelunkers explore the caves at Lava Beds National Monument just for fun and usually do it unencumbered. In fact, you won’t even need a flashlight to see glyphs inside Big Painted Cave and Symbol Bridge Cave. Created by Modoc Indians about 1,500 years ago, most of this black, white, and red rock art is close to the cave entrances and easy to spot. More challenging caves exist if you dare, or just drive across the park to Petroglyph Point—a massive panel of 5,000 glyphs completely above ground.
