The Tree They
Cut Down
to Study

In the summer of 1964, a graduate student's coring tool got stuck in a bristlecone pine on Wheeler Peak. To free it, he and a Forest Service ranger decided to cut the tree down.

Nobody Knew It Was the Oldest Tree Ever Found Until After It Fell

Donald Currey was studying Little Ice Age climate patterns using bristlecone tree rings. He didn't learn what he'd cut down until he counted the rings on the stump.

Great Basin bristlecone pines are the longest-lived trees on Earth, able to survive for millennia on nothing but hostile, wind-scoured rock near 11,000 feet, kept alive by dense, resin-heavy wood that resists rot and insects, and needles that hang on for over 40 years instead of dropping after one season. In 1964, a University of North Carolina doctoral student named Donald Currey was coring bristlecones on Wheeler Peak to study climate patterns from the Little Ice Age. His increment borer, the standard tool for pulling a thin, harmless sample from a living tree, got stuck partway into one especially large specimen. Currey consulted a U.S. Forest Service district ranger, and the two of them decided the fastest way to get a usable cross-section was to cut the tree down.

Only after the tree was on the ground did anyone count the rings properly: 4,844 of them, making it the oldest tree ever dated at the time, older than the previous record holder, a bristlecone named Methuselah still standing in California. Some estimates that account for a ring count taken slightly off-center put the tree's true age closer to 5,000 years. Either way, a tree that had been alive since before the Egyptian pyramids were finished had just been cut down to measure how old it was.

The Wheeler Peak grove, the most accessible in the park, is a 2.8-mile round trip from the end of the scenic drive.

02Stop Two · The Outcry That Helped Build a Park

A Local Writer Called It Murder, and Nevada Listened

Darwin Lambert, who had named the tree Prometheus, wrote that it had been "casually killed" in the name of science. The backlash helped push Congress to protect the area in 1986.

Darwin Lambert, a Great Basin local who had given the tree its name, did not take the felling quietly. Writing in Audubon magazine, he called it "casually killed (yes murdered!) in the name of science," and the phrase stuck. Local advocates and the National Parks Conservation Association picked up the cause, arguing that a landscape capable of growing something nearly 5,000 years old deserved federal protection, not the kind of unregulated access that let one grad student's stuck coring tool end in a chainsaw.

It took more than two decades, but Congress established Great Basin National Park in 1986, protecting Wheeler Peak, its bristlecone groves, and the rest of the surrounding high desert. Prometheus itself never got any more famous in death than the felling made it, its stump and rings are still studied today, cited in climate research the tree's own death helped make possible. Every bristlecone still standing on Wheeler Peak now grows inside a national park that exists partly because one of its neighbors didn't survive to see it.

From Outcry to Protection
  • Public reaction DARWIN LAMBERT, AUDUBON MAGAZINE
  • Advocacy NATIONAL PARKS CONSERVATION ASSOCIATION
  • Park established 1986
  • Protects WHEELER PEAK & BRISTLECONE GROVES
•Sourcing

Bristlecone pine longevity science checked against the National Park Service's official page on bristlecone pines. The Prometheus felling, Donald Currey's research purpose, the ring count, and the age discrepancy between sources checked against the National Parks Conservation Association's published account and the National Park Service's own bristlecone grove trail page, which cites a differing estimate; both figures are presented here since the sources do not fully agree. Darwin Lambert's reaction and the connection to Great Basin National Park's 1986 establishment checked against the National Parks Conservation Association's account.

Stand in the Wheeler Peak grove today and it's hard to tell which trees are merely old and which are ancient beyond easy comprehension, they all look more or less the same: twisted, half-dead, stubbornly alive. Prometheus isn't there anymore to compare against. What's there instead is a park that measures its own age in decades, built around trees that measure theirs in millennia, because for one summer in 1964, the difference between the two got cut down to find out.
