Methuselah
At 4,841 years old, this ancient bristlecone pine is the oldest known non-clonal organism on Earth. Located in the White Mountains of California, in Inyo National Forest, Methuselah's exact location is kept a close secret in order to protect it from the public. (An older specimen named Prometheus, which was more than 5,000 years old, was cut down by a U.S. Forest Service graduate student in 1964.) Today you can visit the grove where Methuselah hides, but you'll have to guess at which tree it is. Could this one be it?
