Sequoiadendron giganteum is the sole living species in the genus Sequoiadendron, and one of three species of coniferous trees known as redwoods, classified in the family Cupressaceae in the subfamily Sequoioideae, together with Sequoia sempervirens and Metasequoia glyptostroboides. Giant sequoia specimens are the most massive trees on Earth. The common use of the name sequoia usually refers to Sequoiadendron giganteum, which occurs 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, to protect 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.
The Giant Sequoia National Monument is a 328,000-acre (1,330 km2) U.S. National Monument located in the southern Sierra Nevada in eastern central California. It is administered by the U.S. Forest Service as part of the Sequoia National Forest and includes 38 of the 39 Giant Sequoia groves that are located in the Sequoia National Forest, about half of the sequoia groves currently in existence, including one of the ten largest Giant Sequoias, the Boole Tree, which is 269 feet high with a base circumference of 112 feet. The forest covers 824 square miles.
The Kaweah River is a river draining the southern Sierra Nevada in Tulare County, California in the United States. Fed primarily by high elevation snowmelt along the Great Western Divide, the Kaweah begins as four forks in Sequoia National Park, where the watershed is noted for its alpine scenery and its dense concentrations of giant sequoias, the largest trees on Earth. It then flows in a southwest direction to Lake Kaweah – the only major reservoir on the river – and into the San Joaquin Valley, where it diverges into multiple channels across an alluvial plain around Visalia. With its Middle Fork headwaters starting at almost 13,000 feet (4,000 m) above sea level, the river has a vertical drop of nearly two and a half miles (4.0 km) on its short run to the San Joaquin Valley, making it one of the steepest river drainages in the United States. Although the main stem of the Kaweah is only 33.6 miles (54.1 km) long, its total length including headwaters and lower branches is nearly 100 miles (160 km).
Redwood Mountain Grove is the largest grove of giant sequoia trees on earth. It is located in Kings Canyon National Park and Giant Sequoia National Monument on the western slope of California's Sierra Nevada. The grove contains the world's tallest giant sequoia. The Hart Tree and Roosevelt Tree grow in the grove and are two of the 25 largest trees by volume in the world. The largest tree is the General Sherman Tree in the Giant Forest grove to the southeast.
The Giant Forest, famed for its giant sequoia trees, is within the United States' Sequoia National Park. This montane forest, situated at over 6,000 ft (1,800 m) above mean sea level in the western Sierra Nevada of California, covers an area of 1,880 acres (7.6 km2). The Giant Forest is the most accessible of all giant sequoia groves, as it has over 40 mi (64 km) of hiking trails.
Freeman Creek Grove is a grove of giant sequoias located in Giant Sequoia National Monument in the Sierra Nevada in eastern California. The area is a botanical reserve under administration by the Sequoia National Forest, except for one small inholding. The largest unlogged grove outside of a national park, it covers about 1,425 acres (5.77 km2) in the Freeman Creek Watershed, mainly south of Freeman Creek. Freeman Creek itself is a tributary of the Kern River.
Alder Creek Grove is a giant sequoia grove located both on private land and within the Giant Sequoia National Monument in the western Sierra Nevada of California. The grove is spread out over approximately 785 acres (318 ha) of land and contains 483 giant sequoias that are at least 25.5 feet in diameter, including the Stagg Tree, the 5th largest tree in the world and one of the oldest known living giant sequoias. Though on private land, the Rouch family made part of their land accessible to the public.
Mountain Home Grove is a grove of giant sequoia trees located in the southern part of the Sierra Nevada Mountains of California, and includes some of the largest trees in the world.
Black Mountain Grove is a large sequoia grove containing more than 500 large trees, on the slopes of Black Mountain located between the Middle and South Forks of Tule River. It lies partly in the Tule River Indian Reservation. Black Mountain Grove is 19.3 miles long and is the sixth largest specimens in the world of all groves. It is dry and hot during summer time which is potentially negative to the forest because it is a higher risk for wildfires. During the winter time, it is cold and fresh. The Black Mountain Grove was a highlight in history because it was the conventional point to stop logging in groves. It played a significant role in the creation of Giant Sequoia National Monument.
The Boole Tree is a giant sequoia in the Converse Basin Grove of Giant Sequoia National Monument, in the Sierra Nevada, in Fresno County, California.
The Stagg Tree, officially the Amos Alonzo Stagg Tree and formerly known as the Day Tree, is a giant sequoia in Alder Creek Grove in California's Sierra Nevada mountains. It is the fifth largest tree in the world and the tallest giant sequoia south of Lincoln in Sequoia National Park. Stagg features the second largest footprint of any living giant sequoia, measuring 109 ft (33 m) in circumference at ground level, and second only to Boole. The tree is believed to be over 3,000 years old, making it one of the oldest living giant sequoias.
The Genesis Tree is a giant sequoia that is the seventh largest tree in the world. It is located within the Mountain Home Grove, a giant sequoia grove located in Mountain Home Demonstration State Forest in the Sierra Nevada of eastern California. The Genesis Tree was heavily damaged by the Castle Fire in 2020.
Franklin is a giant sequoia in Giant Forest, a sequoia grove where the largest tree in the world lives - the General Sherman. The Franklin tree is the eighth largest giant sequoia in the world. It was named by Wendell Flint after Benjamin Franklin. Nearby trees include the Washington Tree which was once the second largest tree in the world, but since it lost half its trunk in 2005 many sequoias are now larger.
The Adam Tree is a giant sequoia located in Mountain Home Grove, a sequoia grove in Giant Sequoia National Monument in the Sierra Nevada of California. It is the 21st largest giant sequoia in the world, and could be considered the 20th largest depending on how badly Ishi Giant atrophied during the Rough Fire in 2015.
Sequoia Crest is a census-designated place (CDP) in Tulare County, California.The community of Sequoia Crest contains more than 150 Giant Sequoias scattered throughout the subdivision. Sequoia Crest sits at an elevation of 7,008 feet (2,136 m). The 2010 United States census reported Sequoia Crest's population was 10. Sequoia Crest can be reached from Porterville by 41 curvy miles most on California State Route 190 with an elevation gain of 6,549 feet.
The Hercules Tree in the Mountain Home Grove of California is a living giant sequoia tree that has a room carved into the center of it. It is also known as the "Room Tree".
