Bristlecone pines

Though they are not human-made artifacts, the ancient bristlecone pine trees found on the arid mountain slopes of the Western United States are among the oldest things on this list. And they are still alive today. In fact, these small, oddly shaped trees are considered to be the oldest living organisms on earth. They grow on mountain slopes just below the tree line starting at about a mile above sea level.

The most ancient of these trees are estimated to be more than 5,000 years old, and there are numerous "younger" specimens that are two to three millennia old. Despite their age, bristlecones are not very tall because of the short growing seasons at the high elevations. The bristlecone's thick needles and many shallow roots make it possible to survive on very little water. This, along with their isolated location, is why they are able to live for so long.
