Half Dome

Half Dome is a granite summit in Yosemite National Park that rises 2,693 meters with a vertical rock face of around 1,360 feet on its northern side. The peak sits at the eastern end of Yosemite Valley and is visible from several trails.

Glaciers shaped this summit over millions of years by carving through the granite block, causing large rock slabs to fall from vertical cracks. Geologists still discuss how much material was removed by erosion.

The Ahwahneechee called this peak Tissiak and told stories of two travelers who turned to stone during an argument. Hikers today see these massive granite walls rising from the forests of Yosemite Valley.

The National Park Service requires permits for the cables route between May and October, with daily access limited to 300 hikers. Visitors should start early since the climb takes several hours and afternoon thunderstorms are common.

The granite structure shows remnants of missing rock projecting from its rim, indicating the original formation was larger than today. Climbers see these leftovers clearly along the northwestern edge.
