Ancient Bristlecone Pine Forest is a protected high-elevation forest in the White Mountains of eastern California, where harsh, dry alpine conditions have helped Great Basin bristlecone pines survive for extraordinary spans of time. Known worldwide for these ancient trees, the forest includes Methuselah Grove, home to “Methuselah,” a bristlecone pine dated to 4,857 years old and long regarded as the oldest known confirmed living non-clonal organism, and Patriarch Grove, home to the Patriarch Tree, described as the world’s largest bristlecone pine. Despite a 2008 arson fire that destroyed the Schulman Grove Visitor Center, the forest was rebuilt and remains prized for endurance, age, and stark beauty.
