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 34,005 cubic feet (962.9 m3), making it the 26th-largest living giant sequoia.
The Grizzly Giant is the oldest sequoia in the Mariposa Grove,[1] 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,[2] 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).[citation needed]
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.[3]
