Prometheus, the 5,000-Year-Old Tree, Was the World’s Oldest—Then It Fell to a Scientist’s Axe

In 1964, a seemingly innocent request led to the destruction of a nearly 5,000-year-old tree, now known as Prometheus. This Great Basin bristlecone pine, located in Nevada’s Wheeler Peak, had stood through millennia, silently bearing witness to history. But, when graduate student Donald Rusk Currey sought to cut it down for his research, no one knew the immense age it carried—until it was too late.

Great Basin National Park’s Reflection

The narrative surrounding Prometheus was not just about a young researcher’s mistake but about how an unexpected act of curiosity led to the discovery of one of the oldest living organisms on Earth. “We may never know the true story of what happened,” confirms the Great Basin National Park, suggesting there are several versions of the events leading to Currey’s decision to fell the tree.

One possibility is that Currey needed to retrieve his drill, which had become lodged while taking a core sample. Another is that he believed he needed a full cross-section of the tree to complete a more comprehensive study on tree rings. What is clear, however, is that Currey had obtained permission from the Forest Service to cut the tree down, but he could never have anticipated the age of what he was about to destroy.

The Staggering Age of Prometheus

When Currey finally returned to his hotel room after cutting down the tree, he meticulously counted the rings in the cross-section, using a magnifying glass. “I knew it was a pretty old tree,” Currey recalled years later in an interview with the San Francisco Chronicle. But when he reached the final count, the result was beyond comprehension—Prometheus was almost 5,000 years old. This revelation was both staggering and tragic. Bristlecone pines, especially those in the Great Basin region, are known for their slow growth, which allows them to survive in harsh climates, often reaching ages that defy belief. Yet their small size, which contrasts with the towering giants of California’s redwood forests, can make their incredible age easy to overlook.

The Unexpected Legacy of Prometheus

Although Currey’s act was one of research, it sparked a wave of reflection on how we view and preserve the natural world, especially ancient organisms. The shock of discovering the tree’s age led to a broader awareness of the longevity of bristlecone pines. Despite the fact that Currey did not fell the oldest tree on Earth, it did lead to further studies that uncovered trees in other forests that might be even older than Prometheus. Many of these trees remain unstudied, hidden within isolated locations like California’s White Mountains.

Currey’s story is now a cautionary tale in the scientific community, one that has influenced how federal lands are managed today. According to the park, “It’s not going to happen again,” as modern-day tree conservation practices are more vigilant. Ancient trees like Prometheus are now protected, their existence celebrated and studied from a distance rather than cut down for analysis.

The Importance of Dendrochronology

Dendrochronology—the study of tree rings—has evolved significantly since the 1960s. Initially, methods of counting rings were far more rudimentary, often leading to inaccurate conclusions about a tree’s age. However, with the advent of more refined techniques and cross-dating methods, scientists have become more adept at determining the true ages of trees, making the destruction of an ancient tree like Prometheus even more tragic in hindsight. Bristlecone pines, with their unique adaptation to survive harsh environments, can continue living even after sustaining significant damage. This makes them resilient, but also fragile, in the sense that the destruction of their trunks can prevent them from contributing further to the study of history.
