The Grizzly Giant is a Giant Sequoia thought to be the oldest living tree in Yosemite National Park and one of the largest living trees in the world. The Grizzly Giant is located in the southernmost region of Yosemite Park in Mariposa Grove, the largest stand of Giant Sequoias in the park. It is estimated that the Grizzly Giant is between 1900-2400 years old and has been listed as the 25th largest tree in the world. The Yosemite Grizzly Giant has an estimated wood volume of 34,010 cubic feet.
The basal circumference, which is heavily buttressed due to fire damage and environmental stress, measures 92 feet or a diameter of 30 feet. The tree stands 210 feet high and it's first branch growing off the trunk is 6 feet in diameter. The Grizzly Giant has been damaged by many lightening fires throughout it's ancient existence and it's trunk bears some of these scars. The top of the tree has also been burned away from fires and damaged by wind like many of the other Giant Sequoias that call Yosemite home.
