The Volcanic Tableland offers exceptional bouldering opportunities, because of its unique geologic features formed by the cataclysmic volcanic eruption of the Long Valley Caldera 750,000 years ago, which left a highly dissected landscape of Bishop Tuff. Through time, this once barren tableau has evolved to support a unique and fragile environment that takes a keen eye and time to appreciate. The Volcanic Tablelands is situated at the ecological cusp of the Northern Mojave and Great Basin floristic Provinces where plants and associated wildlife species combine to make this an unusual and biologically diverse landscape. It has taken millennia for this environment to evolve and it will take responsible recreational users to preserve it into perpetuity - so enjoy and protect this place
