Half dome yosemite

Half Dome, the iconic granite monolith in Yosemite National Park, attracts hikers worldwide with its distinctive shape and challenging trail.

About this subject

Half Dome is a granite formation located in Yosemite National Park, California, United States. Standing at 2,694 meters (8,839 feet) above sea level, it rises approximately 1,460 meters (4,800 feet) above the Yosemite Valley. Its distinctive shape, a rounded dome split by a vertical cliff, results from millions of years of glacial erosion and weathering. The rock is primarily Cretaceous granite, formed by slow cooling of magma beneath the Earth's surface.

The trail to the summit of Half Dome is one of the most famous and strenuous in the United States. It covers about 14 miles (23 km) round trip with an elevation gain of 4,800 feet (1,460 meters). The final section involves climbing steel cables fixed to the rock face, requiring physical fitness and preparation. The park requires a permit for the climb, obtained via lottery or advance reservation, limiting daily visitors to ensure safety and environmental preservation.

Culturally, Half Dome is an icon of the American West, appearing in countless photographs, paintings, and films. The indigenous Ahwahneechee people called the rock "Tis-sa-ack," referencing a legend about a woman whose tears formed the vertical face. Today, besides hikers, it attracts geologists and tourists who admire panoramic views of Yosemite Valley, waterfalls, and the giant sequoias in the region.
