Knowledge gets expensive when it arrives too late. The scientists who have made the most consequential mistakes in the history of conservation were not careless people. They were trained, credentialed, methodical, and working inside the normal parameters of their discipline. The thing they didn’t know was simply the thing nobody knew yet, and by the time the knowing arrived, the thing itself was already gone. That particular sequence has repeated itself enough times across enough fields that you’d think we would have developed some kind of institutional instinct for it. We haven’t. We just keep finding out after.
The story of Prometheus is the story of that exact sequence, compressed into a single summer morning in 1964 on a Nevada mountainside. A graduate student. A broken drill. A form filed with the Forest Service. A crew with chainsaws who had done this kind of thing before. None of them had any reason to believe the job was anything other than routine, because nothing in their training or experience had given them a reason to think otherwise.
The tree had been standing there since before the Great Pyramid at Giza was finished, which is the sort of sentence that takes two seconds to read and much longer to actually sit still with. It had no sign, no roped perimeter, no designation. Just a gnarly bristlecone pine doing what bristlecone pines do, which is exist at altitude with a patience that makes everything human look like a blink.
The Man With the Drill
In 1963, Donald Rusk Currey was a graduate student at the University of North Carolina at Chapel Hill, working under a fellowship from the National Science Foundation, studying the climate dynamics of the Little Ice Age using dendrochronology techniques. Dendrochronology, for the uninitiated, is simply the science of reading tree rings: each ring laid down each year, thicker rings for good years, thinner ones for hard ones, the whole cross-section a kind of compressed autobiography of a life lived in weather.
Currey was studying climate dynamics of the Little Ice Age using dendrochronology techniques. In 1963, he became aware of the bristlecone populations in the Snake Range in general, and on Wheeler Peak in particular. The bristlecone pine had already attracted serious scientific attention. Bristlecone pines in California’s White Mountains had been discovered by Edmund Schulman to be older than any species yet found, spurring interest in finding very old bristlecones – possibly older than the Methuselah tree, which Schulman had aged at over 4,700 years in 1957.
Currey hiked up Wheeler Peak with a tool called a Swedish increment borer – essentially a hollow, threaded drill that extracts a thin core sample from a living tree. The core comes out no wider than a soda straw, the tree survives the extraction, and the researcher gets the ring data they need without killing anything. It is elegant and non-destructive, which is presumably why it became the standard method. Based on the size, growth rate, and growth forms of some of the trees he encountered, Currey became convinced that very old specimens existed on the mountain, and he began taking core samples – finding that some exceeded 3,000 years in age, taking particular interest in a tree he designated WPN-114.
WPN-114. The designation meant it was the 114th tree he had sampled in his research in Nevada’s White Pine County. A file number. A notation in a notebook. Nothing about it suggested the tree was anything other than old, interesting, and usable. Currey chose this particular specimen for his study because it seemed older than much of the surrounding forest, with a single living bark strip supporting a branch of lush foliage.
The Borer Breaks
According to the Wikipedia record of Currey’s work, he was unable to obtain a continuous series of overlapping cores from WPN-114: he had tried at least four times with a 28-inch-long borer, breaking two borers in the process, but to no avail. He decided to ask the United States Forest Service to authorize the felling of the tree.
The precise reason for the request has remained contested ever since. Some accounts state that Currey got his increment borer stuck in the tree and, needing to retrieve it for subsequent work, asked the U.S. Forest Service to cut it down. Other accounts say the gnarly shape of the tree simply didn’t allow Currey to get good samples with his borer, so he concluded he had to cut it down to get complete cross-sections of the trunk. Currey himself, in his 1965 paper, offered a somewhat different rationale still – indicating that he sectioned the tree as much over the question of whether the oldest bristlecones were necessarily confined to California’s White Mountains as from its usefulness in relation to studies of the Little Ice Age.
Whatever the exact chain of reasoning, authorization was granted. The tree was cut and sectioned on August 6, 1964, and several pieces of the sections were hauled out to be processed and analyzed. A Forest Service crew with chainsaws did the work. The whole operation was entirely routine. Nobody present had any reason to think it was anything else.
The Counting
According to the National Parks Conservation Association, Currey brought a slab from the lower part of the tree back to his lab and started counting the rings. Soon, he had counted back 1,000 years to the Vikings, then back to the time of the Roman Empire and gladiators. But he was only halfway finished.
Read that again for a moment. Halfway through the count, and already at ancient Rome.
In the end, the pine’s cross-section had 4,844 annual rings. At that point, the oldest known organism was several decades younger – a bristlecone pine in California named Methuselah. Hoping he’d miscounted, Currey began the tedious process again. But no matter how many times he counted the rings, the number never decreased. In other words, he had discovered the oldest tree ever dated. But he had killed it.
Currey originally estimated the tree was at least 4,844 years old. A few years later, this count was increased to 4,862 by Donald Graybill of the University of Arizona’s Laboratory of Tree-Ring Research. These ring counts were done on a trunk cross-section taken about eight feet above the original germination point of the tree, because the innermost rings were missing below that point – meaning the actual age was almost certainly higher still. The tree that Currey had drilled at, struggled with, and eventually cut down was, in all likelihood, well past its 4,900th year.
To put that in human terms: the tree that fell on a Nevada mountainside in August 1964 had been alive when the ancient Egyptians were still building their earliest cities. It had been alive during the Bronze Age, the Iron Age, the rise and fall of multiple civilizations, the construction of Stonehenge, the founding of Rome, the entire span of recorded Western history. And for all of that, it had gone entirely unnoticed by the people who came and went below it, until the one morning a graduate student’s drill snapped in its wood.
The Tree That Grew Into Something Else
Prometheus, recorded as WPN-114), was the world’s oldest known non-clonal organism – a Great Basin bristlecone pine (Pinus longaeva) growing near the tree line on Wheeler Peak in eastern Nevada. The name came before Currey ever arrived. Beginning in the 1950s, naturalists had given names to several of the largest or most distinctive bristlecone pines in the area – there were Buddha, Socrates, Methuselah, and of course Prometheus, which had been named by Great Basin native Darwin Lambert.
The name was well chosen. In Greek mythology, Prometheus is the figure who stole fire from the gods and gave it to humanity – an act of profound, consequential knowledge transfer that came at enormous personal cost. The tree named after him did something similar: it gave dendrochronologists a new understanding of how ancient living things could be, transformed the scientific conversation around tree conservation, and changed the way a generation of researchers thought about what they were dealing with when they went to work in old-growth forests. All of it at the cost of its own life.
Part of what makes bristlecone pines so extraordinary is precisely what makes them easy to overlook. Living conditions at their elevation are harsh, winds are high, and the growing season is very short. Yet these ancients continue to thrive, even though they grow so slowly that some years they don’t lay down a ring at all. This slow growth makes the wood dense and resistant to insects, fungi, rot, and erosion. A 40-year-old bristlecone pine may not even reach six inches tall. In harsh conditions, bristlecone pines stop growing in height altogether, but their trunk diameter continues to increase throughout their lives. Size, in other words, tells you almost nothing about age. The most ancient things in the grove might be the most unassuming ones.
You can still visit what remains of Prometheus. The stump is all that remains of the ancient giant within the grove. If you would like to travel through history by counting the rings yourself, you can do so at the Great Basin National Park visitor center in Baker, Nevada. Pieces of the tree also ended up distributed to various institutions – sections ended up at the Ely Convention Center; the University of Arizona Laboratory of Tree-Ring Research; and the U.S. Forest Service’s Institute of Forest Genetics in Placerville, California.
What the Cutting Changed
It took a few years for information about the felling of Prometheus to reach the public, but once it did, there was great controversy. Most criticism centered on the U.S. Forest Service’s decision to permit the tree to be cut. Some critics pointed out the obvious: questions were raised about how the cutting of such an old tree was necessary at all, given the topic Currey was studying – since the Little Ice Age started no more than 600 years ago, many trees could presumably have provided the information he needed for that time period.
Currey himself eventually refused to speak publicly about the incident. He came in for a great deal of blame in subsequent years and eventually stopped talking about it, though he went on to become a highly regarded geography professor at the University of Utah. He died at age 70 on June 6, 2004.
The cutting had one significant, lasting consequence that nobody planned for. The loss of WPN-114 caused a national controversy as news of the cutting became known. The tree lived in Humboldt National Forest near Wheeler Peak, the second-highest mountain in Nevada. Local advocates had long wanted the area to be reclassified as a national park, and they seized on the loss of Prometheus as evidence for their position. Great Basin National Park was established by an act of Congress on October 27, 1986. The destruction of one ancient tree, in other words, helped bring into existence the protected land that now preserves thousands of others.
Bristlecone pines are now protected across all federal land. The scientific community’s attitude toward living specimens in old-growth study sites shifted significantly in the decades following Prometheus. As one researcher noted to Collectors Weekly, the mindset in 1964 was simply that trees were a renewable resource – “it didn’t seem like it was any particularly special tree.” That particular mindset did not survive the counting of WPN-114’s rings.
Since Prometheus fell, the record has continued to evolve. Methuselah, a Great Basin bristlecone pine in the White Mountains of California, has been measured by ring count to be 4,857 years old and is therefore the oldest known living individual non-clonal tree in the world. A still-older candidate was identified in the same mountain range – a living bristlecone pine measured by Tom Harlan in 2010 to be 5,062 years old, though this pine has not been found following Harlan’s death in 2013, and its core has not been located at the Laboratory of Tree-Ring Research. Its location was deliberately kept secret, which now feels like the right instinct.
What Stays on the Mountain
There is a particular kind of grief for something that was lost before anyone understood what it was. Not the grief of watching something decline – that gives you time to argue, to fight, to organize a protest and mail letters to the Forest Service. This is the grief of finding out only after. The rings were counted, the fact was established, and the tree was already gone. All that was left was the addition: nearly 5,000 years, plus whatever months remained in the summer of 1964.
The stump is still up there on Wheeler Peak, buried in snow for much of the year, slowly being reclaimed by the same harsh environment that made the tree extraordinary in the first place. Researchers and conservationists have visited it, excavated it, photographed it, scanned it – trying to document what remains of something that will never come back. The rings that were there are still there, compressed in wood that has resisted weathering for sixty years since the chainsaw. Dense, resinous, bristlecone-stubborn to the last.
What Prometheus left behind is not a clean lesson. It is a complicated one – the kind science accumulates in the gap between what it knew at the time and what it learned too late. Science made a mistake that came from not knowing what it was dealing with. That happens. What changed afterward – the protections, the park, the shift in how researchers treat living specimens – came directly from the weight of that mistake pressing down on the people who had to reckon with it. The archive, as they say, never gets smaller, only larger. And sometimes the most important entry in it is the one you didn’t mean to make.
