At an estimated 13,200,000 lbs with an age of roughly 80,000 years, the giant Redwood found its match. By an Aspen tree? Pando is a Quaking Aspen tree, and thought to be the heaviest known organism on planet Earth. Located in Utah, this Aspen tree’s mass is primarily hidden underground, taking up over 100 acres of space.[1] At first glance a single Aspen tree can appear to be a group of several trees. When infact, the Aspen tree can have many clones connected by a single root system underground. Fascinating![2]
