Yosemite National Park is a national park in California. It is bordered on the southeast by Sierra National Forest and on the northwest by Stanislaus National Forest. The park is managed by the National Park Service and covers 759,620 acres in four counties – centered in Tuolumne and Mariposa, extending north and east to Mono and south to Madera. Designated a World Heritage Site in 1984, Yosemite is internationally recognized for its cliffs, waterfalls, clear streams, giant sequoia groves, lakes, mountains, meadows, glaciers, and biological diversity. Almost 95 percent of the park is designated wilderness. Yosemite is one of the largest and least fragmented habitat blocks in the Sierra Nevada.
Sequoiadendron giganteum, also known as the giant sequoia, giant redwood or Sierra redwood is a coniferous tree, classified in the family Cupressaceae in the subfamily Sequoioideae. Giant sequoia specimens are the most massive trees on Earth. They occur naturally only in groves on the western slopes of the Sierra Nevada mountain range of California.
Sequoia National Park is an American national park in the southern Sierra Nevada east of Visalia, California. The park was established on September 25, 1890, and today protects 404,064 acres of forested mountainous terrain. Encompassing a vertical relief of nearly 13,000 feet (4,000 m), the park contains the highest point in the contiguous United States, Mount Whitney, at 14,505 feet (4,421 m) above sea level. The park is south of, and contiguous with, Kings Canyon National Park; both parks are administered by the National Park Service together as the Sequoia and Kings Canyon National Parks. UNESCO designated the areas as Sequoia-Kings Canyon Biosphere Reserve in 1976.

Calaveras Big Trees State Park is a state park of California, United States, preserving two groves of giant sequoia trees. It is located 4 miles (6.4 km) northeast of Arnold, California in the middle elevations of the Sierra Nevada. It has been a major tourist attraction since 1852, when the existence of the trees was first widely reported, and is considered the longest continuously operated tourist facility in California.
Nelder Grove, located in the western Sierra Nevada within the Sierra National Forest in Madera County, California, is a Giant sequoia grove that was formerly known as Fresno Grove. The grove is a 1,540-acre (6.2 km2) tract containing 54 mature Giant Sequoia trees, the largest concentration of giant sequoias in the Sierra National Forest. The grove also contains several historical points of interest, including pioneer cabins and giant sequoia stumps left by 19th century loggers.
Human habitation in the Sierra Nevada region of California reaches back 8,000 to 10,000 years ago. Historically attested Native American populations, such as the Sierra Miwok, Mono and Paiute, belong to the Uto-Aztecan and Utian phyla. In the mid-19th century, a band of Native Americans called the Ahwahnechee lived in Yosemite Valley. The California Gold Rush greatly increased the number of non-indigenous people in the region. Tensions between Native Americans and white settlers escalated into the Mariposa War. As part of this conflict, settler James Savage led the Mariposa Battalion into Yosemite Valley in 1851, in pursuit of Ahwaneechees led by Chief Tenaya. The California state military forces burned the tribe's villages, destroyed their food stores, killed the chief's sons, and forced the tribe out of Yosemite. Accounts from the Mariposa Battalion, especially from Dr. Lafayette Bunnell, popularized Yosemite Valley as a scenic wonder.
Galen Clark was a Canadian-born American conservationist and writer. He is known as the first European American to discover the Mariposa Grove of Giant Sequoia trees, and is notable for his role in gaining legislation to protect it and the Yosemite area, and for 24 years serving as Guardian of Yosemite National Park.
The Wawona Hotel is a historic hotel located within southern Yosemite National Park, in California. It was declared a National Historic Landmark in 1987, and is on the National Register of Historic Places.
The Chandelier Tree in Drive-Thru Tree Park is a 276-foot (84 m) tall coast redwood tree in Leggett, California with a 6-foot-wide (1.8 m) by 6-foot-9-inch-high (2.06 m) hole cut through its base to allow a car to drive through. Its base measures 16 ft (4.9 m) diameter at breast height (chest-high). A historic sign put up in or before the 1930s claims a height of 315 feet high and 21 feet wide, but a contemporary measurement by a Certified Arborist experienced with tall redwoods and using a laser rangefinder found the tree to be 276 feet high and 16 feet in diameter. It is unknown if the tree was topped by Nature in between the measurements.
The Wawona Tree, also known as the Wawona Tunnel Tree, was a famous giant sequoia that stood in Mariposa Grove, Yosemite National Park, California, USA, until February 1969. It had a height of 227 feet (69 m) and was 26 feet (7.9 m) in diameter at the base.
The Wawona Tunnel is a highway tunnel in Yosemite National Park. It, and Tunnel View just beyond its east portal, were completed in 1933.
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.
Yosemite National Park is located in the central Sierra Nevada of California. Three wilderness areas are adjacent to Yosemite: the Ansel Adams Wilderness to the southeast, the Hoover Wilderness to the northeast, and the Emigrant Wilderness to the north.
The Pioneer Cabin Tree, also known as The Tunnel Tree, was a giant sequoia in Calaveras Big Trees State Park, California. It was considered one of the U.S.'s most famous trees, and drew thousands of visitors annually. It was estimated to have been more than 1,000 years old, and measured 33 feet (10 m) in diameter; its exact age and height were not known. The tree was topped before 1859. It fell and shattered during a storm on January 8, 2017.
Nelder is a giant sequoia located within the Nelder Grove of Sequoia National Forest in California. It is the largest tree in Nelder Grove, the 23rd largest giant sequoia in the world, and could be considered the 22nd largest depending on how badly Ishi Giant atrophied during the Rough Fire in 2015.
The Washburn Fire was a wildfire that burned in Yosemite National Park near the Mariposa Grove of giant sequoias. The fire was reported on July 7, 2022, in the lower Mariposa Grove area near the Washburn trail, for which the fire is named. The fire quickly attracted national attention due in part to the role the Mariposa Grove played in the establishment of Yosemite National Park and the National Park Service.
Guardian of the Wilderness is a 1976 theatrical narrative film directed by David O'Malley about the true story of Galen Clark, an explorer who successfully campaigned to have the Yosemite area set aside from commercial development, the original forerunner of the American national parks system. Clark was prompted by his dedication to preserving places like the Mariposa Grove of Giant Sequoias, which he discovered, from being destroyed by loggers. The cast features Denver Pyle as Galen Clark, John Dehner as legendary naturalist John Muir and Ford Rainey as Abraham Lincoln. Clark was eventually appointed Superintendent of Yosemite, a position in which he served for more than two decades during which he defined the concept of an American park ranger; his varied history with the valley ranged across 55 years.
