Discussion Great Basin bristlecone pine has the longest life span of any nonclonal species in the world. The oldest known living Great Basin bristlecone pine had 4,862 countable annual rings when it was cut on Wheeler Peak in 1974. Downed trees in the White Mountains lived over 5,000 years before they fell. The oldest living organism known is a bristlecone pine tree nicknamed "Methuselah". Located in the Ancient Bristlecone Pine Forest in the White Mountains of eastern California; its precise location undisclosed to protect the tree. Three closely related species of bristlecone pine:
Rocky Mountains Bristlecone Pine: Pinus aristata in Colorado, New Mexico and Arizona
Great Basin Bristlecone: Pine Pinus longaeva in Utah, Nevada and eastern California
Foxtail Pine: Pinus balfouriana in California.
