Half Dome, which stands nearly 8,800 feet (2,682 meters) above sea level, is composed of granodiorite, and is the remains of a magma chamber that cooled slowly and crystallized thousands of feet beneath the Earth's surface.

Half Dome is a quartz monzonite batholith at the eastern end of Yosemite Valley in Yosemite National Park, California. It is a well-known rock formation in the park, named for its distinct shape. One side is a sheer face while the other three sides are smooth and round, making it appear like a dome cut in half.
22 Αυγ 2023 · The landscape of Yosemite National Park is a product of its unique geology, resulting from glacial erosion of the underlying granite. Iconic landforms such as Yosemite Valley, Yosemite Falls, Bridalveil Fall, El Capitan, Half Dome, and Cathedral Peak are known throughout the world.
10 Νοε 2023 · Looking east toward the head of Yosemite Valley, you can see Half Dome, a massive rock formation with a rounded summit and a sheer face that looks like it's been cut in half. Half Dome is one of the most well-known features in Yosemite.
Half Dome is one of the indisputable monarchs of Yosemite National Park, a lopsided, sheer fin soaring high above Yosemite Valley. Considering how Half Dome formed introduces you to the wonders of Sierra Nevada geology —which involves both molten fire and bulldozing ice!
Large, relatively unjointed volumes of granite form domes such as Half Dome and monoliths like the 3,604 ft (1,098 m) high El Capitan. Closely spaced joints lead to the creation of columns, pillars, and pinnacles such as Washington Column , Cathedral Spires, and Split Pinnacle.
Yosemite National Park is notable because it contains classic examples of domes, such as Half Dome. These domes began to form during this period of uplift when the overlying rock eroded and the confining pressure on the pluton (solidified magma chamber) was removed, and exfoliation created rounded domes.
