Cache Creek Wilderness sits on a bed of serpentine rock -- greenish stone forged from peridotite deep in Earth's subduction zones, then thrust to the surface carrying a cocktail of asbestos, mercury, copper, and magnesium that kills most plants on contact. Most, but not all. Over millennia, a specialized flora evolved to thrive in what would be lethal ground for ordinary species, and approximately twenty percent of California's rare and endemic plants grow exclusively in soils like these. What looks from the air like rough, half-barren hill country is in fact one of the state's most botanically significant landscapes.
