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 on July 6, 2015, for a restoration project and reopened on June 15, 2018.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. It has a volume of 34,010 cubic feet (963 m3), and is counted as the 25th largest tree in the world. It is 210 feet (64 m) tall, and has a heavily buttressed base with a basal circumference of 28 m (92 ft) or a diameter of 30 feet (9.1 m); 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. Abraham Lincoln signed an Act of Congress on June 30, 1864, ceding Mariposa Grove and Yosemite Valley to the state of California. Criticism of stewardship over the land led to the state's returning the grove to federal control with the establishment of Yosemite National Park. The Mariposa Grove Museum is listed on the National Register of Historic Places.

Calaveras County, officially the County of Calaveras, is a county in the northern part of the U.S. state of California. As of the 2010 census, the population was 40,171. The county seat is San Andreas. Angels Camp is the county's only incorporated city. Calaveras is Spanish for "skulls"; the county was reportedly named for the remains of Native Americans discovered by the Spanish explorer Captain Gabriel Moraga. Calaveras County is in both the Gold Country and High Sierra regions. Calaveras Big Trees State Park, a preserve of giant sequoia trees, is in the county several miles east of the town of Arnold on State Highway 4. Credit for the discovery of giant sequoias there is given to Augustus T. Dowd, a trapper who made the discovery in 1852 while tracking a bear. When the bark from the "Discovery Tree" was removed and taken on tour around the world, the trees became a worldwide sensation and one of the county's first tourist attractions. The uncommon gold telluride mineral calaverite was discovered in the county in 1861 and is named for it. Mark Twain set his story "The Celebrated Jumping Frog of Calaveras County" in the county. The county hosts an annual fair and Jumping Frog Jubilee, featuring a frog-jumping contest, to celebrate the association with Twain's story. Each year's winner is commemorated with a brass plaque mounted in the sidewalk of downtown Historic Angels Camp and this feature is known as the Frog Hop of Fame. In 2015, Calaveras County had the highest rate of suicide deaths in the United States, with 49.1 per 100,000 people.
