This tree is called "Prometheus". Prometheus was the nickname given to the oldest known non-clonal organism, a Great Basin Bristlecone Pine (Pinus longaeva) tree growing near the tree line on Wheeler Peak in eastern Nevada, USA. The tree, which was at least 4862 years old and likely approaching or over 5000 years, was cut down in 1964 by a graduate student and U.S. Forest Service personnel for research purposes. They did not know of its world-record age before the cutting.
However, the circumstances and decision making process leading to the felling of the tree remain controversial, with different extant versions regarding the decision to cut the tree; not all of the basic facts are agreed upon by all involved. The nickname of the tree refers to the mythological figure Prometheus, who stole fire from the gods and gave it to man.
The girth of this tree is not known. This tree was planted around the year 2898 BC ± 10, which makes it around 4911 ± 10 years old (Tim B, Oct 1, 2011).
