Bristlecone Pine are reported to be the oldest iving specimen on earth, having measured some of these wonders to be in excess of 4500 years old...this grove is located at 12,000 foot elevation in the White Mountains on the California/Nevada state border... Patriarch Grove, here pictured, survives on very limited moisture.
I just completed a trip to the Eastern Sierra's but did not have time for the Bristlecone Forest. After seeing these photos I will definitely get there the next time.
