Half Dome

Half Dome is a rock formation at the eastern end of Yosemite Valley, and may be the Valley's most familiar sight. The granite crest rises more then 1440 meters (4737 feet) above the Valley floor.

As late as 1870, Half Dome was considered completely unclimbable, but it may now be ascended in two different ways. Thousands of hikers reach the top each year by following a trail from the valley floor. The trailhead is only two miles from Half Dome itself, but the circuitous route is 8.5 miles (13.5 kilometers) long. The final ascent is accomplished by following a pair of metal cables raised on posts up the peak's steep but somewhat rounded east face.

Alternatively, several rock climbing routes lead directly from the valley up Half Dome's sheer north face.
