Hyperion tree

From Wikipedia, the free encyclopedia

This article is about Hyperion, the tallest living tree. For other uses, see Hyperion (disambiguation).
Hyperion is the name of a Coast Redwood (Sequoia sempervirens) in Northern California that was confirmed to measure 115.61 metres (379.3 ft), which ranks it as the world's tallest known living tree.[1] Despite its great height, Hyperion is not the largest known coast redwood; that distinction belongs to the Lost Monarch tree.
Hyperion was discovered August 25, 2006 by naturalists Chris Atkins and Michael Taylor.[2] The tree was verified as standing 115.55 m (379.1 ft) tall by Stephen Sillett. The tree was found in a remote area of the Redwood National Park purchased in 1978, during the Carter Administration. The exact location of the tree has not been revealed to the public for fear that human traffic would upset the ecosystem the tree inhabits. The tree is estimated to contain 502 m3 (18,600 cubic feet) of wood,[3] and to be roughly 700 – 800 years old.[4]
Researchers stated that woodpecker damage at the top prevented the tree from reaching 380 feet (115.8 m).[4]
