Grizzly Giant

The Grizzly Giant is a giant sequoia in Yosemite National Park's Mariposa Grove. It has been measured many times; in 1990 Wendell Flint calculated its volume at 34005 cuft, making it the 26th-largest living giant sequoia.

The Grizzly Giant is the oldest sequoia in the Mariposa Grove, the largest giant sequoia grove in Yosemite National Park, with several hundred mature specimens. At one time, the Grizzly Giant was considered the oldest and largest tree in the world, aged between 2,000 and 3,000 years. In 2019, refined scientific dating methods resulted in a new age estimate for the Grizzly Giant: 2,995 years old (plus or minus 250 years).

On July 16, 2022, the Washburn Fire threatened Grizzly Giant and other trees in Mariposa Grove. The National Park Service used sprinklers to protect the famous tree.
