Height:96.7 m

The tallest known Sitka spruce in the world is Raven Spruce which is 96.7 m (96.68 m) tall.

Exact location of this enormous tree is not diclosed but it is known that the tree is located in Prairie Creek Redwoods State Park. This park was established in the 1920s in order to protect redwood forests with extremely tall and large trees whose growth has been facilitated by the very frequent fogs.

Raven's Tower was discovered and measured by Ron Hildebrandt and Michael Taylor in 2001, measured also by Steve Sillett in 2007.

Tree has lively top, seems to be growing and by now might be taller.

Bark of Sitka spruce is friendly to epiphytes and in the moist, foggy climate the trees get covered with diverse moss, lichens and ferns. Branches of trees get thick cover and even soil developing on them - and as a result high above the ground, at the height of 50 m spruce develops new network of roots on its own branches! This should be of great assistance to achieve greater height of the tree because exactly the extreme lift of nutrients from the roots is limiting the height of the trees.
