Where is the oldest living tree?

The oldest verified individual tree on Earth is a Great Basin bristlecone pine growing high in the White Mountains of eastern California, whose age has been dated to over 4,850 years by counting its growth rings, meaning it sprouted before the Egyptian pyramids were finished. For decades the most famous ancient bristlecone was named Methuselah, and an even older specimen has since been reported in the same region. These gnarled, weather-beaten trees survive in harsh, dry, high-altitude conditions that few plants can tolerate, and their slow growth and dense wood help them resist rot and pests. Some clonal organisms, such as a colony of quaking aspen called Pando in Utah that shares a single root system, are far older as a whole, and certain clonal shrubs may be tens of thousands of years old.
