4,900 year old bristlecone pine tree |
Some Great Basin bristlecone pines are more than 4,000 years old.
'The main attraction of the White Mountains is the Ancient Bristlecone Pine Forest. The bristlecone pine trees are 3000-4000 years old, and are alive despite their dead appearance. They can survive in the dry, harsh limestone environment, where other trees cannot.
Scientists have pieced together tree-rings from bristlecone pine trees and extended the record to 8680 years into the past. This is used to calibrate radioactive carbon dating, giving the bristlecone pine the name 'The tree that rewrote history'.'
