Methuselah is a living Great Basin bristlecone pine in California’s White Mountains, estimated to be about 4,800 years old. It was already growing as construction of the Pyramids of Giza began. Its exact location is kept secret to protect the tree.

How old is the Methuselah tree?

Methuselah’s age is an estimate based on tree-ring research, not a newly confirmed count of its age today. Official sources publish slightly different figures: the National Park Service gives 4,765 years, NASA gives 4,770, and a 2011 U.S. Forest Service article reports more than 4,789 years, based on core samples taken in 1957.

Those differences reflect published estimates from different sources and dates. The useful takeaway is that Methuselah is approximately 4,800 years old; no cited source establishes an exact present-day age or a universally accepted current ranking as the oldest tree.

Where is Methuselah?

Methuselah grows in the Ancient Bristlecone Pine Forest in California’s White Mountains. The individual tree’s location is deliberately undisclosed. The National Park Service says exact locations of older trees are kept secret, and the Forest Service says the measure is intended to protect Methuselah from vandalism.

Can you visit the Methuselah Trail?

Visitors can hike among ancient bristlecone pines without being told which tree is Methuselah. The Inyo National Forest’s 2021 visitor guide describes the Methuselah Trail as a moderate 4.5-mile loop. It lists the visitor center as open from late spring to fall, weather permitting. Because that guide is dated, check current Forest Service visitor information for trail conditions and seasonal operations before traveling.

Was Methuselah growing when the Egyptian pyramids were built?

NASA’s comparison is that Egyptians were just beginning construction of the Pyramids of Giza when Methuselah took root. So it is fair to say the tree was already growing as construction began. The comparison does not mean Methuselah predates every Egyptian pyramid by thousands of years.

Why can bristlecone pines live so long?

Great Basin bristlecones are adapted to harsh, high-elevation environments. In old trees, only a narrow strip of living tissue may connect the roots to a few branches. As roots or sections of a tree die, other parts can continue living; cold, dry conditions also slow fungal growth and wood decay. These are explanations for the species’ longevity, not documented measurements of Methuselah’s individual biology.

Their rings also preserve records of past growing conditions. Researchers use bristlecone chronologies in climate research and archaeology, and tree-ring records help calibrate radiocarbon dating. A ring’s width reflects growing conditions, making the trees valuable as long-term environmental records as well as living organisms.

What happened to the Prometheus tree?

Prometheus was a different bristlecone pine, not another name for Methuselah. It was cut down in 1964 with Forest Service permission for research. Later counts found 4,862 growth rings, and the tree was estimated to have been 4,900 years old. The estimate exceeded the ring count because harsh conditions can prevent a tree from forming a ring every year.

The National Park Service also reports a bristlecone found in the White Mountains and dated in 2012 at 5,065 years old. That is not Methuselah. Comparisons of very old trees need to distinguish living trees from felled ones, individual trees from clonal organisms, and ring counts from estimates of elapsed years.
