Stratosphere Giant

Stratosphere Giant was a coast redwood that had, at one point, been the tallest tree in the world. In July 2000, the tree was discovered in Humboldt Redwoods State Park, measuring 368.6 ft (112.34 m) tall. It has continued to grow, and officially reached a height of 371.1 ft (113.11 m) high in 2010. It is surrounded by several other trees of almost equal size. To avoid damage by tourism, the tree's exact location remains undisclosed to the public.

The Stratosphere Giant was surpassed on August 25, 2006, when naturalists, Chris Atkins and Michael Taylor discovered Hyperion in Redwood National Park, which measures 379.1 ft (115.55 m) high. Two other trees in this forest, Helios and Icarus, were found to be taller than the Stratosphere Giant as well.
