Stratosphere Giant was once considered the tallest tree in the world.[1] It was discovered in July 2000 in Humboldt Redwoods State Park, measuring 112.34 metres (368.6 ft) tall.[2] The tree has continued to grow and measured 113.11 m (371.1 ft) in 2010.[3] It is a specimen of the species Sequoia sempervirens, the Coast Redwood. It is surrounded by a large number of trees of almost equal size. To avoid damage by tourism, the tree's exact location was not disclosed to the public.
On August 25, 2006, a redwood named Hyperion in the Redwood National Park was discovered by Chris Atkins and Michael Taylor, and is considered the tallest tree (and living thing), measuring 115.55 m (379.1 ft). This has been confirmed using a tape measurement. Two other trees in this forest were found to be taller than Stratosphere Giant as well.[2]
