Yosemite National Park and the granite walls of Yosemite Valley

Yosemite National Park centres on Yosemite Valley, a granite-walled glacial canyon in California’s Sierra Nevada; its cliffs and waterfalls define the landscape.

Yosemite National Park in California’s Sierra Nevada centres on Yosemite Valley, a glacial canyon where sheer granite walls rise above the Merced River and forested floor. Established on 1 October 1890 and designated a UNESCO World Heritage site in 1984, the park preserves mountain scenery that has become a defining image of the Sierra Nevada in the United States.

Granite, glaciers and the making of Yosemite Valley

Yosemite National Park lies on the western slope of the Sierra Nevada, an asymmetric mountain range in central California near the state’s eastern border.western slope of the Sierra Nevada Yosemite Valley itself is carved largely in granites and granodiorites of Cretaceous age, emplaced deep underground as large plutons before being exposed at the surface.granites and granodiorites of Cretaceous age

Over geological time, tectonic uplift raised the Sierra Nevada and steepened the course of the Merced River, helping the river to cut down into its canyon. Later, during Ice Age conditions, glaciers moved through what became Yosemite Valley and scoured its walls into the steep, cliff-lined profile seen from the valley floor.glaciers moved through what became Yosemite Valley The result is a classic U-shaped valley where vertical joints in the granite have been opened into towering monoliths and alcoves.

Cliffs, waterfalls and giant sequoias

Within the park, granite cliffs, waterfalls, clear streams, lakes, meadows and groves of giant sequoias form a varied mountain landscape.granite cliffs, waterfalls, clear streams Yosemite Valley concentrates many of these elements in a single, relatively compact space: high cliffs rise from the valley floor, waterfalls plunge over their edges in spring and early summer, and the Merced River meanders through open meadows lined with conifers and broadleaf trees.

Beyond the valley, the park’s groves of giant sequoias stand as some of the most distinctive trees in the Sierra Nevada, with massive trunks and spreading crowns.groves of giant sequoias High country lakes and subalpine meadows lie at greater elevation, backed by rugged peaks including Mount Lyell, which rises above 4,000 m (13,000 ft) and forms the park’s highest point.Mount Lyell, the park’s highest point

A protected mountain landscape and its scale

Yosemite National Park covers in the region of 759,000 acres, equivalent to just over 1,180 square miles, and most of this area is designated wilderness where roads and permanent structures are absent.759,620 acres of protected land Park headquarters stand at Yosemite Village in Yosemite Valley, placing administration within the canyon that many visitors know best.park headquarters at Yosemite Village

Formally, Yosemite National Park lies within Tuolumne, Mariposa, Mono and Madera counties in east-central California, surrounded by national forest land.Tuolumne, Mariposa, Mono and Madera counties The valley itself occupies the west-central part of the park and serves as a starting point for excursions into higher basins and passes such as Tioga Pass, which crosses the high crest of the Sierra Nevada.

Visiting Yosemite National Park: what travellers from Western Europe should know

• Yosemite National Park lies in east-central California on the western slope of the Sierra Nevada, with Yosemite Valley reached by road from settlements in Mariposa and the wider Central Valley.
• The terrain in Yosemite Valley includes level meadow paths, forest tracks and steeper trails that climb from the valley floor to viewpoints on the surrounding cliffs.
• Higher areas of the park rise above 3,000 m (about 10,000 ft), so routes into the high country involve significant elevation and correspondingly cooler mountain conditions.
• The official language is English and the currency is the US dollar.
• Entry requirements depend on your nationality; UK travellers can check the FCDO travel advice at gov.uk/foreign-travel-advice, Irish travellers the Department of Foreign Affairs at ireland.ie.
