The oldest known bristlecone pine tree is "Methuselah", which is 4,789 years old. To keep Methuselah from harm, this tree isn't labeled, as the other trees are. An older tree called Prometheus was killed shortly after it was discovered in 1964. This happened when a geologist searching for evidence of Ice Age glaciers was taking some core samples from several bristlecones. Just as he realized he had found a tree over 4,000 years old, his coring tool broke. Amazingly the U.S. Forest Service gave him permission to cut down the tree. Prometheus turned out to be 4,950 years old. It was a 300 year old tree when the pyramids were being built in Egypt. After people heard about this incident, the U.S. Forest Service tightened security around the bristlecones. I have planted a dozen bristlecone pines on my farm.

Not knowing what a bristlecone pine tree was , I googled it after reading your post. What a magnificent tree (poem?). Barbara

I've heard that story, incredible, isn't it?
Where did you get your bristlecone pines?
