* * *scenic mountain region in east-central California, U.S. It is situated about 140 miles (225 km) east of the city of San Francisco; Devils Postpile National Monument lies about 15 miles (25 km) to the east and Kings Canyon National Park about 40 miles (65 km) to the southeast. The region was first set aside as a state park in 1864 and, together with additional surrounding territory, was declared a national park in 1890, largely through the efforts of naturalist John Muir (Muir, John). (Muir's article on Yosemite appeared in the 10th edition of the Encyclopædia Britannica [see the Britannica Classic: ].) Designated a World Heritage site in 1984, it encompasses 1,189 square miles (3,080 square km).The park lies in the heart of the Sierra Nevada. The land rises from west to east, the eastern boundary forming a drainage divide. Most of the tallest peaks are in the southeastern area of the park, many exceeding 10,000 feet (3,050 metres); Mount Lyell, at 13,114 feet (3,997 metres), is the highest summit. Glaciation has sculpted a number of deep, U-shaped valleys, notably the Yosemite Valley of the Merced River. The valley features a number of attractions, such as sheer rock walls, Yosemite Falls, and huge domes and peaks. The greatest of these domes is El Capitan, a granite buttress that rises to 7,569 feet (2,307 metres) and towers some 3,600 feet (1,100 metres) above the valley floor.Plant life in the park changes markedly with elevation. Lower elevations are characterized by scattered trees (both deciduous and coniferous), shrubs, and meadows that fill with wildflowers in spring. At the level of Yosemite Valley grow larger stands of conifers that include groves of big trees (the giant sequoias); higher up, closer to the tree line, are mountain hemlocks and lodgepole pines. Animal life includes mule deer, various squirrels, chipmunks, and black bears. Numerous species of birds are found in the park, notably Steller's jays, western meadowlarks, and mountain bluebirds.Yosemite is one of the most heavily visited national parks in the country. Yosemite Valley in particular is highly congested during the summer months. Because of heavy traffic and a lack of parking, a shuttle bus system was created to transport visitors around the valley. A plan was adopted in 2000 to improve conditions in Yosemite by restoring disturbed natural areas, easing traffic congestion with expanded bus service, and renovating lodging facilities. Hiking is popular along the park's hundreds of miles of trails. The Pacific Crest National Scenic Trail cuts across the northeastern portion of the park; before exiting in the east, it is joined by the John Muir Trail, the northern terminus of which is at the head of Yosemite Valley. The Badger Pass Ski Area, to the south of the valley, is a winter recreation centre. The Yosemite Museum contains exhibits on the area's native Miwok and Paiute peoples.
