Yosemite National Park is a national park of the United States 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 granite cliffs, waterfalls, clear streams, groves of giant sequoia, 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.

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 British North America-born American conservationist and writer.

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, United States, 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 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 Rim Fire was a massive wildfire that started in a remote canyon in the Stanislaus National Forest in California's Tuolumne County. The fire ignited on August 17, 2013, amid the 2013 California wildfire season, and burned 257,314 acres in largely remote areas of the Sierra Nevada, including a large portion of Yosemite National Park. The Rim Fire was fully contained on Thursday, October 24, 2013, after a nine-week suppression effort by firefighters. Due to a lack of winter rains, some logs smoldered in the interior portion of the fire footprint throughout the winter, and more than a year passed before the fire was declared totally extinguished in November 2014.
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.

The Ferguson Fire was a major wildfire in the Sierra National Forest, Stanislaus National Forest and Yosemite National Park in California in the United States. The fire was reported on July 13, 2018, burning 96,901 acres (392 km2), before it was 100% contained on August 19, 2018. Interior areas of the fire continued to smolder and burn until September 19, 2018, when InciWeb declared the fire to be inactive. The Ferguson Fire was caused by the superheated fragments of a faulty vehicle catalytic converter igniting vegetation. The fire, which burned mostly in inaccessible wildland areas of the national forest, impacted recreational activities in the area, including in Yosemite National Park, where Yosemite Valley and Wawona were closed. The Ferguson Fire caused at least $171.2 million in damages, with a suppression cost of $118.5 million and economic losses measuring $52.7 million. Two firefighters were killed and nineteen others were injured in the fire.
The SQF Complex fire—also called the SQF Lightning Complex—was a wildfire complex that burned in Tulare County in Central California in 2020.

Begun by a lightning strike in the southern Sierra Nevada on September 9, the fire burned 97,528 acres (39,468 ha) over the course of a month, threatening communities like Ponderosa and Johnsondale. Multiple atmospheric rivers in October and November eventually subdued the fire, which was declared fully contained in mid-November. Total firefighting costs came to $78.4 million. The Windy Fire was the eight-largest fire of California's 2021 wildfire season.
The 2021 KNP Complex Fire was a large wildfire in Sequoia National Park and the Sequoia National Forest in Central California's Tulare County. After lightning ignited the Paradise and Colony fires in the southern Sierra Nevada on September 9, the twin blazes combined into the Complex and burned a total of 88,307 acres. The fire was not declared contained until mid-December, after several atmospheric rivers delivered rain and snow to the mountains. The number of firefighting personnel reached more than 2,000 and firefighting costs surpassed $170 million.
