Mariposa Grove is a sequoia grove located near Wawona, California, United States, in the southernmost part of Yosemite National Park. It is the largest grove of Giant Sequoias in the park, with several hundred mature examples of the tree. Two of its trees are among the 30 largest Giant Sequoias in the world. The grove closed from 2015 to 2017 for a restoration project.The Mariposa Grove was first visited by non-natives in 1857 when Galen Clark and Milton Mann found it. They named the grove after Mariposa County, California, where the grove is located.The Giant Sequoia named Grizzly Giant is between probably 1900–2400 years old: the oldest tree in the grove. In 1932, park officials claimed it as the fifth largest (by volume) tree in the world, but other trees were subsequently found to be larger. It has a volume of 34010cuft, and is counted as the 25th largest tree in the world. It is 210ft tall, and has a heavily buttressed base with a basal circumference of 28 m (92 ft) or a diameter of 30ft; above the buttresses at 2.4 m above ground, the circumference is only 23 m. Grizzly Giant's first branch from the base is 2 m (6 ft) in diameter. Another tree, the Wawona Tree, had a tunnel cut through it in the nineteenth century that was wide enough for horse-drawn carriages and early automobiles to drive through. Weakened by the large opening at its base, the tree fell down in a storm in 1969.
