Half dome yosemite

Half Dome is an iconic granite monolith in Yosemite National Park, California, known for its vertical face and distinctive shape.

About this subject

Half Dome is a granite formation in Yosemite National Park, located in the Sierra Nevada of California. Rising to 2,693 meters, its name comes from the dome-like shape that appears to be split in half, a result of millions of years of differential erosion and glacial activity. The rock is primarily Mesozoic granite, exposed by tectonic and glacial forces. The northwest face features a vertical drop of about 600 meters, making it a famous climbing destination since the 1950s. The trail to the summit, approximately 14 kilometers round trip, includes steel cables installed on the final section to assist hikers. About 50,000 people reach the top annually, though permits are limited by lottery to prevent overcrowding. Half Dome also symbolizes the conservation movement; John Muir and Theodore Roosevelt camped nearby during discussions that led to the park's protection. Notably, the Ahwahnechee Native Americans call it "Tis-sa-ack", referencing a mythological figure.
