Hyperion is a Coast Redwood, and has the distinction of being the tallest living organism ever measured. It is 379.3 feet tall. That’s 38 stories, 100 feet taller than #5, 50 feet taller than the tallest habitable building in Washington, D. C. It grows in Redwood National Park and was not even discovered until 25 August, 2006, because all the trees around it are also redwoods, and are all gargantuan.
Like all redwoods and sequoias (very similar species), Hyperion is so enormous that it possesses its own ecosystem, with full-size pines and hemlocks growing on its branches. It is so high that if you could avoid the branches (and other trees) on the way down, BASE jumping would be no problem at all. There are no confirmed photos of it on the Internet, because scientists don’t want it disturbed or damaged by tourists. Like the Giant Sequoia, you can fit about 10 coast redwood seeds on the face of a dime.
