MessageToEagle.com – Utah’s Pando, also known as the Trembling Giant is one of North America’s most beautiful trees. It is also one of the world’s oldest and most massive living organisms. Located in an aspen colony in Utah’s Fishlake National Forest, Pando is believed to be about 80,000 years old. Some even estimate that Pando could be as old as 1 million years, which would mean Pando predates the earliest Homo sapiens by 800,000 years!

When Pando was discovered scientists named it with a Latin word that means “I spread.”

Pando is is a clonal colony of a single male quaking aspen (Populus tremuloides) determined to be a single living organism by identical genetic markers and assumed to have one massive underground root system.

At nearly 13 million pounds, its and its root system sprawls across 106 acres and feeds of over 40,000 individual trees.
