Hyperion was discovered August 25, 2006, by naturalists Chris Atkins and Michael Taylor. 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 Redwood National and State Parks purchased in 1978. 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 530 m3 (18,600 cu ft) of wood and to be roughly 700–800 years old.
Researchers stated that woodpecker damage at the top may have prevented the tree from growing taller. According to Michael Taylor, "It's possible it could've topped out at 380 feet [or 116 metres]".
