The Grizzly Giant is a massive giant sequoia located in Mariposa Grove within Yosemite National Park. Famous for its impressive size and age, the Grizzly Giant has been a symbol of the park since tourism began. [1] The Grizzly Giant stands out with its enormous trunk, which is much larger than typical giant sequoias, and its unique, uneven branches shaped by centuries of weather and environmental factors. [1] Its name comes from its imposing presence, reminiscent of a California grizzly bear. [1]

The Grizzly Giant is the oldest tree in Mariposa Grove, which is Yosemite National Park's largest grove of giant sequoias, containing hundreds of mature trees. [2] Although once considered the oldest and largest tree in the world, recent dating techniques have estimated the Grizzly Giant’s age at about 2,995 years, with a margin of error of plus or minus 250 years. [3] [4] [5] In 1990, the tree's volume was measured at 34,005 cubic feet (962.9 m3), making it the 26th-largest living giant sequoia. [6] [7]

Nineteenth-century photographs and paintings of the Grizzly Giant vividly showcased the immense scale and beauty of giant sequoias, convincing a skeptical public of their existence and spurring early conservation efforts that ultimately protected Mariposa Grove.

On July 16, 2022, the Washburn Fire threatened Grizzly Giant and other trees in Mariposa Grove. The National Park Service used sprinklers to protect the famous tree. [8]

In 1859, publisher James M. Hutchings, on the advice of naturalist Galen Clark, named the tree the Grizzled Giant. [10] [11] By 1888, it was commonly known as the Grizzly Giant. Hutchings said the tree "looks at you as defiantly as the oldest veteran grizzly bear ever could." [12]

The Grizzly Giant was once believed to be much older, with David Starr Jordan estimating its age at 8,000 to 10,000 years. [13] [14]

The tree has endured severe fire damage over the centuries, losing over 80% of its bark and sapwood, along with significant heartwood. This damage has limited its nutrient intake, slowing its growth and healing. In addition to fire, the tree has faced countless storms, including one in 1942 when it was struck by lightning six times. [13]

Since 1904, the Grizzly Giant has been closely monitored due to its significant 18-foot lean. [15] Despite weighing an estimated 3,700 tons, the tree remains balanced through its naturally curved structure, strategically placed branches, and a robust root system. [13] In 1912, a wire fence was installed around the tree's base to stop visitors from damaging it by hacking off pieces of bark for souvenirs. [16]

The tree has hosted visits from notable figures, including Presidents Roosevelt in 1903 and Taft in 1909. [17] [18]

Visual Arts

Photography and paintings of the Grizzly Giant significantly shaped 19th-century views of giant sequoias and played a key role in the conservation efforts that protected Mariposa Grove.

Photography

Carelton Watkins' photographs of the Grizzly Giant in the 1860s captured more than its size; they bridged a continental divide. A key image, showing the tree towering over people at its base, made the enormity of giant sequoias clear to Eastern audiences cut off by the American Civil War. These photographs dispelled doubts about the so-called 'California Hoax,' convincing academics and the public of the giant sequoias' existence and sparking both fascination and scientific study. [19] : 102–110  Botanist Asa Gray was particularly struck by these photos. He acquired Watkins' full collection, using them in a 1872 American Association for the Advancement of Science lecture. [20] His presentation highlighted the sequoia’s ecological importance, driving further research and ultimately, conservation efforts that would lead to state protection of Mariposa Grove. [19]

Painting

In the 1870s, Albert Bierstadt, a key figure of the Hudson River School, painted the Grizzly Giant's grandeur in The Great Trees, Mariposa Grove, California. [21] : 46–47  Inspired during his 1871-1873 visits to Yosemite and Mariposa Grove, Bierstadt completed the expansive five-by-ten-foot canvas in 1876. [22] The painting, inspired by Watkins' renowned photograph and displayed at the Centennial Exposition in Philadelphia, broadened public exposure to the West's natural beauty, reinforced support for the conservation movement, and echoed themes of manifest destiny.

<span class="mw-page-title-main">History of the Yosemite area</span>

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.

<i>Guardian of the Wilderness</i> 1976 American film

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.
