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.
Kings Canyon National Park is an American national park in the southern Sierra Nevada, in Fresno and Tulare Counties, California. Originally established in 1890 as General Grant National Park, the park was greatly expanded and renamed on March 4, 1940. The park's namesake, Kings Canyon, is a rugged glacier-carved valley more than a mile (1,600 m) deep. Other natural features include multiple 14,000-foot (4,300 m) peaks, high mountain meadows, swift-flowing rivers, and some of the world's largest stands of giant sequoia trees. Kings Canyon is north of and contiguous with Sequoia National Park, and both parks are jointly administered by the National Park Service as the Sequoia and Kings Canyon National Parks.
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.
General Grant Grove, a section of the greater Kings Canyon National Park, was established by the U.S. Congress in 1890 and is located in Fresno County, California. The primary attraction of General Grant Grove is the giant sequoia trees that populate the grove. General Grant Grove's most well-known tree is called General Grant, which is 267 ft (81 m) tall and the third-largest known tree in the world. The General Grant tree is over 1,500 years old and is known as the United States' national Christmas tree. General Grant Grove consists of 154 acres (0.62 km2) and is geographically isolated from the rest of Kings Canyon National Park.
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.
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.
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.
Sequoia National Forest is located in the southern Sierra Nevada mountains of California. The U.S. National Forest is named for the majestic Giant Sequoia trees which populate 38 distinct groves within the boundaries of the forest.
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.
Mother of the Forest was a giant sequoia in the Sierra Nevada that was stripped of its bark and used as an exhibition tree. Discovered in 1852 by Augustus T. Dowd, it was the second largest tree in Calaveras Grove, standing at 328 feet tall with a circumference of 93 feet. During the California Gold Rush, its bark was harvested and exhibited in New York and London. However, the remaining tree was eventually destroyed by fire in 1908, leaving only a fire-blackened snag.
Converse Basin Grove is a grove of giant sequoia trees in the Giant Sequoia National Monument in the Sierra Nevada, in Fresno County, California, 5 miles (8 km) north of General Grant Grove, just outside Kings Canyon National Park. Once home to the second-largest population of giant sequoias in the world, covering 4,600 acres (19 km2) acres, the grove was extensively logged by the Sanger Lumber Company at the turn of the 20th century. The clearcutting of 8,000 giant sequoias, many of which were over 2,000 years old, resulted in the destruction of the old-growth forest ecosystem.
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.
The General Noble Tree was a monumental giant sequoia situated in the Converse Basin Grove, within the boundaries of the Giant Sequoia National Monument, in Fresno County, California. It was believed to be the biggest tree in the world before its felling in 1892 for an exhibit at the World's Columbian Exposition in Chicago. It was the largest tree ever felled.
The Hume-Bennett Lumber Company was a logging operation in the Sequoia National Forest in the late 19th and early 20th centuries. The company and its predecessors were known for building the world's longest log flume and the first multiple-arch hydroelectric dam. However, the company also engaged in destructive clearcutting logging practices, cutting down 8,000 giant sequoias in Converse Basin in a decade-long event that has been described as "the greatest orgy of destructive lumbering in the history of the world."
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 Discovery Tree also known as The Mammoth Tree was a giant sequoia tree located in Calaveras Grove, California. In the spring of 1852, A.T. Dowd stumbled upon a hidden grove in the Sierra Nevada, and with it, the existence of giant sequoias was revealed to the world. Among the magnificent trees he encountered stood the Discovery Tree, a towering 300-foot giant with a base measuring over 24 feet in diameter. But this natural wonder would soon become a symbol of humanity's destructive impact. The Discovery Tree was cut down and shipped to San Francisco and New York City for exhibition, its grandeur reduced to a mere spectacle for profit. Yet, its legacy lived on as a rallying cry for conservation efforts. The tree's fate played a crucial role in the introduction of the Yosemite Grant to Congress, an act that helped preserve and protect these ancient giants for future generations. Today, the stump of the Discovery Tree remains a popular attraction in Calaveras Grove, which draws 200,000 visitors each year.
