Visiting Yosemite National Park in the Western United States
Situated in the Sierra Nevada Mountains, Yosemite National Park covers an area of 3,081 square kilometers and is one of California's most famous destinations.
In the days of President Abraham Lincoln, Galen Clark was the first European American to discover part of the wooded grove and the spectacular Yosemite Valley, 300 miles east of San Francisco. He and many others actively campaigned to preserve this newly discovered area. Soon after, the land of Yosemite was decided by Congress and President Lincoln to be used only for recreation and picnic. The "Yosemite Grant Act" was signed on June 30, 1864 to allocate to California State for the management and protection of the forests of Mariposa and the Yosemite Valley.
Later, the naturalist John Muir ("Father of National Parks") and several other researchers have advocated expanding the reserve to more mountainous areas surrounding the Yosemite Valley. By October 1, 1890, Yosemite National Park was officially established. The movement of John Muir also contributed to the formation of the American National Park system. In 1984, Yosemite was recognized by UNESCO as World Natural Heritage.
Scientists said that about 10 million years ago, the topography here was strongly raised, which formed the shape of the Sierra Nevada mountains with cliffs slightly inclined to the west, and vertical to the east. Due to this impact, rivers and streams were elevated, which created deep and narrow canyons.
It was here that about a million years ago a glacier formed over a thousand meters, when the giant glacier moved, it hewn the canyons to form cliffs and an U shape of the he Yosemite Valley is as beautiful as it is today.
Half Domem Mountain
The park has a variety of granite rock formations, ranging from 600 to 4,000m above sea level, including 16 mountains including Hoffmann (3,085m), Maclure (3,658m), Clark (3,353m) and Lyell (3,962m). The most spectacular view, Half Dome with the height of 2,438 m above sea level, has become a symbol of Yosemite. Half Dome with El Capitan (1,095m) is an ideal climbing point for many climbers around the world.
Visitors on Hoffmann Mountain
In the parking lot there is information, floating maps and clean toilets.
Forest protection and fire prevention are introduced into general education.
Natural regenerated trees
Five diverse ecosystems are closely related to minerals from the ground (such as granodiorite) and vegetation. About 3,500 California plant species are found in the Sierra Nevada and more than 1,500 in the Yosemite Valley, of which more than 160 species are rare plants.
The park is also home to many wild animals, such as black bear (Ursus americanus) presented on the California flag, and about 500 individuals in Yosemite with color from brown to black. Visitors are also easy to see small animals such as gray rabbit (Lepus sp.), Mule deer (Odocoileus hemionus), squirrel (Sciuridea family) with more than 10 species, etc.
