The oldest tree species is the Great Basin bristlecone pine (Pinus longaeva). 

The oldest tree of the species is named Methuselah and is more than 4,800 years old. 

The longevity of the Great Basin bristlecone pine can be attributed to factors such as the species' ability to withstand various weather conditions, including intense winds, snow and rain. Its unique, twisted shape comes from the tree's adaptation to these types of intense weather, according to the National Park Service's website.

The oldest Great Basin bristlecone pine is one named Methuselah. 

Sources vary on the exact age of the oldest tree. Guinness World Records clocks the tree at 4,856 years old as of 2024.

Though Methuselah holds the title of oldest in the species, there are several Great Basin bristlecone pines that are over 4,000 years old, according to the U.S. Park Service website. 

In addition to the Great Basin bristlecone pine being able to withstand harsh weather, the tree also grows uniquely, a contributor to its longevity.

The tree's roots feed the sections of the tree that are directly above them, according to the National Park Service. This means that if a root dies, only that particular section of the tree that is being fed through that particular root dies along with it and the rest of the tree keeps growing strong. 

The Great Basin bristlecone pine is a very rare species. 

The trees can be found in California, Nevada and Utah, according to the National Park Service website. 

Great Basin National Park in Nevada is one spot where you can get a close-up look at the ancient trees. 

There are three Great Basin bristlecone pine groves located in the park, which are Wheeler Peak, Mount Washington and Eagle Peak, according to the National Park Service. 

The Nevada national park offers hikes for all levels as well as scenic drives that are filled with Great Basin bristlecone pines to view.

Another national park filled with the ancient tree species is Bryce Canyon National Park in Utah.

To see the Great Basin bristlecone pines in Utah, take a hike on the Fairyland Loop trail or the Bristlecone Loop trail at Rainbow Point, according to the National Park Service. 

The Bristlecone Loop is home to the oldest tree in the park, which can be found at Yovimpa Point and is around 1,600 years old, according to the source. 

You can also view trees of the species on the Peekaboo Loop trail and along the Rim Trail. 

Inyo National Forest in California is a third spot where Great Basin bristlecone pines can be spotted. 

This park, Patriarch Grove specifically, is where the world's largest Great Basin bristlecone pine can be found, according to the U.S. Forest Service. 

The oldest Great Basin bristlecone pine was discovered in 1957 by a researcher named Edmund Schulman, according to Live Science. 

The tree was given a proper age by taking cores of other Great Basin bristlecone pines in the area and counting rings, per the source. 

Before Methuselah, the oldest tree of the species was Prometheus, a tree on Wheeler Peak that was around 4,900 years old when it was chopped down in 1964. 

The tree was cut down by a geographer named Donald R. Currey, who was conducting research at the time into ice age glaciology, according to the National Park Service.

The United States Forest Service gave Currey permission to take core samples from Great Basin bristlecone pines in the area. 

Later analysis found that the tree cut down by Currey had 4,862 growth rings, according to the National Park Service, but the now-chopped tree was thought to have dated back even further than that. 

Methuselah is located in the Inyo National Forest, according to the USDA website, but its exact location remains under wraps by the U.S. Forest Service for its protection.
