About this subject

Half Dome is one of the most iconic rock formations in Yosemite National Park, California, USA. Standing at 2,693 meters (8,836 feet) above sea level, it rises approximately 1,440 meters (4,724 feet) above the Yosemite Valley. Its east face is a near-vertical granite cliff over 600 meters (2,000 feet) high, while the west side has a gentler slope, created by glacial activity during the last ice age.

Geologically, Half Dome is composed of granite formed about 87 million years ago during the Cretaceous period. The rock originated from the slow cooling of magma deep underground and was later exposed by erosion. During glaciations, glaciers sculpted the east face, creating a profile that resembles a dome cut in half. This process is similar to that which formed El Capitan, another famous monolith in the park.

The first documented ascent of the Regular Northwest Face was in 1957, led by Royal Robbins, Mike Sherrick, and Jerry Gallwas, using big wall climbing techniques. Today, this route is a world classic, with thousands of attempts each year. For non-climbers, the summit can be reached via the cables route, installed in 1919, which requires a lottery permit and good physical fitness. About 50,000 people make the trek each summer.

Culturally, Half Dome is a symbol of Yosemite National Park and the environmental conservation movement. It was immortalized by photographer Ansel Adams in black-and-white images that helped promote the park's creation. The silhouette of Half Dome appears in logos, films, and artworks, representing the majesty of the American wilderness.
