Ancient Bristlecone Pine Forest
The Ancient Bristlecone Pine Forest is a protected area high in the White Mountains in Inyo County in eastern California. Geography
The forest is east of the Owens Valley, high on the eastern face of the White Mountains in the upper Fish Lake-Soda Spring Watershed, above the northernmost reach of the Mojave Desert into Great Basin ecotone. The forest's mountain habitat is in the Central Basin and Range ecoregion (EPA) and Taiga and Boreal forest ecoregion (WWF). The Patriarch Grove is the source of Cottonwood Creek, a designated Wild and Scenic River. Ecology

The Great Basin bristlecone pine (Pinus longaeva) trees grow between 9,800 and 11,000 feet (3,000–3,400 m) above sea level, in xeric alpine conditions, protected within the Inyo National Forest. Limber pine (Pinus flexilis) also grow in the forest. Methuselah
The Methuselah Grove in the Ancient Bristlecone Pine Forest is the location of the "Methuselah", a Great Basin bristlecone pine that is  years old. It is considered to be the world's oldest known and confirmed living non-clonal organism. It was temporarily superseded by a 5,062 year old bristlecone pine discovered in 2010. In May 2017 however, Dr. Peter Brown removed this tree from his database of old trees because the tree and core sample could not be found. "Methuselah" is not marked in the forest, to ensure added protection from vandals. Visiting
