Humboldt Redwood State Park

Humboldt Redwoods State, containing Rockefeller Forest, the world's largest remaining contiguous old-growth forest of coast redwoods.


The park was established by the Save the Redwoods League in 1921 largely from lands purchased from the Pacific Lumber Company. It is part of the Northern California coastal forests eco-region and has 96 km2 of old-growth forests. Over 100 of the 137 known trees over 110m tall—all coast redwoods—occur in Humboldt Redwoods State Park. It is home to the 4th-tallest measured living redwood, theStratosphere Giant, which was measured at 112.94 metres in 2004.


The park is famed for its coast redwoods (Sequoia sempervirens), many of which grow to over 90 m in height. The forests on are almost redwood forest, but the forests on the slopes also contain Douglas-fir.


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