Humboldt Redwoods State Park - Redwoods

Redwoods

The park is famed for its coast redwoods (Sequoia sempervirens), many of which grow to over 300 feet (91 m) in height. The forests on alluvial plains are almost pure redwood forest, but the forests on the slopes also contain Coast Douglas-fir.

Over 100 of the 137 known trees over 350 feet (110 m) tall—all coast redwoods—occur in Humboldt Redwoods State Park. It is home to the 4th-tallest measured living redwood, the Stratosphere Giant, which was measured at 112.94 metres (370.5 ft) in 2004. Stratosphere Giant was the tallest known living redwood until the discovery of three taller trees in Redwood National Park; the tallest, Hyperion, measuring 115.55 metres (379.1 ft) in September 2006.

Before the discovery of Hyperion, the tallest redwood ever measured was the Dyerville Giant, also in Humboldt Redwoods State Park. It was 113.4 metres (372 ft) high when it fell in March 1991. It was estimated to be 1,600 years old.
