Quaking aspens are the ubiquitous tree in Utah. Seen as a scourge in the city because you can never, NEVER, get rid of them, they are nevertheless a beautiful tree. In the summer, their brilliant green leaves shimmer and shake and tremble with the slightest breeze. In the fall, they have a blazing yellow circle of a leaf and the bare white and black bark stand out starkly against the snow in winter. One reason we see so many quakies is their unique way of propagating, by sending up shoots from a massive root system. One colony, named Pando, is considered the heaviest and oldest living organism in the world. It is six million kilograms and about 80,000 years old… and is located right in the middle of the state of Utah.
