The Volcanic Tablelands near Bishop, California, are a vast, rugged landscape formed over 700,000 years ago by the Long Valley caldera. In this high desert environment, generations of Paiute and Shoshone Indians once resided, leaving behind an extensive collection of carefully chiseled petroglyphs in the rocks. Now a destination for rock climbers, these fragile treasures are protected by the Bureau of Land Management. Photo by Abhilash Itharaju (www.sharetheexperience.org).
