Millions of years ago, Half Dome was larger than it is today, but it never sported a matching half in front of the sheer cliff face. Deep inside the great hunk of rock, a broad vertical crack was exposed when glaciers flowed by and undercut Half Dome’s base.
Half Dome is a granite dome 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.
The Half Dome Cable Route hike runs from the valley floor to the top of the dome in 8. 2 mi (13 km) (via the Mist Trail), with 4,800 ft (1,460 m) of elevation gain. The length and difficulty of the trail used to keep it less crowded than other park trails, but in recent years the trail traffic has grown to as many as 800 people a day.
The last segment of the hike up Yosemite’s Half Dome is nerve-wracking to many, but deaths there are rare. In the almost 100 years since cables were installed to help hikers climb the steep pitch of the dome, nine people have died from falling on that stretch. Of those fatal falls, at least five occurred when the rock was wet.
When did Half Dome break?
July 5, 2015: The climb to the top of Half Dome just became harder. A huge sheet of granite measuring 100 by 200 feet fell off the face and created a “rockfall” below.

How were El Capitan and Half Dome formed?

What is Half Dome known for?

How old is Half Dome?
The domes were formed about 65 million years ago, when molten, igneous rock solidified into granite deep within the Earth and was pushed up under pressure to the surface. The granite was shaped into domes as the uplifted, curved layers of rock cleaved off.
How did the Half Dome formed?
A large vertical fracture in the granite formed a weakness that glaciers could exploit, leading to the sheer face of Half Dome. The summit of Half Dome was never overtopped by glaciers, so its rounded shape results from a different kind of erosion called exfoliation.
What is so special about El Capitan?
1. At more than 1/2 a mile (3,000u2032) high and 1 mile wide, El Capitan is the tallest exposed vertical face of granite on earth. 2. It’s more than twice the height of the Empire State Building, which is 1,250u2032 tall.
Why is it named El Capitan?
The formation was named “El Capitan” by the Mariposa Battalion when they explored the valley in 1851. El Capitxe1n (“the captain”, “the chief”) was taken to be a loose Spanish translation of the local Native American name for the cliff, variously transcribed as “To-to-kon oo-lah” or “To-tock-ah-noo-lah” (Miwok language).
