This standing tree may have died hundreds of years ago. Scientific matching of dead trees' growth rings with living ones has created a 9,000-year-long record. Bristlecone pines are known for attaining great ages. The oldest bristlecone pine in the White Mountains is Methuselah, which has a verified age of 4,856 years.
