Time Traveling with a Tree


The Bristlecone pine is slow growing and old, with some trees in the White mountains of California living over 4,500 years. Even after death this pines’ timber stays around for a very long time, allowing scientists to study this plant to learn what the world was like some 9,000 years ago.
