While Pando isn’t technically the oldest individual tree, this clonal colony of Quaking Aspen in Utah is truly ancient. The 105-acre colony is made of genetically identical trees, called stems, connected by a single root system. The “trembling giant” got its start at least 80,000 years ago, when all of our human ancestors were still living in Africa. But some estimate the woodland could be as old as 1 million years, which would mean Pando predates the earliest Homo sapiens by 800,000 years. At 6,615 tons, Pando is also one of the heaviest living organism on earth.
Methuselah - The world’s oldest individual tree lives 10,000 feet above sea level in the Inyo National Forest, California. A staggering 4,765 years old, this primeval tree was already a century old when the first pyramid was built in Egypt. The tree is hidden among other millennia-old Great Basin bristlecone pines in a grove called the Forest of Ancients. To protect the tree from vandalism, the forest service keeps its exact location secret, but this one looks like it could be Methuselah.
