Glacier Point

Glacier Point is a viewpoint above Yosemite Valley, in California, United States. It is located on the south wall of Yosemite Valley at an elevation of 7214ft, 3200ft above Half Dome Village. The point offers a superb view of several of Yosemite National Park's well-known landmarks including Yosemite Valley, Yosemite Falls, Half Dome, Vernal Fall, Nevada Fall, and Clouds Rest.GeologyThe extreme point of the promontory of Glacier Point is wholly bare, but on the slopes below, in the hollow to the west, and on the wooded slope above, glacial material is abundant. Its glacial origin is definitely proved by the presence in it of rocks derived from Little Yosemite Valley and the High SierraThere are three types of glacially-deposited rock at Glacier Point: Most plentiful are rounded boulders and cobbles and angular fragments, all deeply weathered, of Half Dome quartz monzonite, the light-colored granite of which not only Half Dome, but all of the Little Yosemite and its surrounding heights are composed.There are also a few boulders of a coarse-grained, highly siliceous granite, light buff in general tone when fresh but vivid rose when weathered. There is only one place in the High Sierra above the Yosemite from which they can be derived: Mount Clark, the sharp-profiled peak which stands on the east side of the Illilouette Basin, 8mi from Glacier Point.Finally, there are fragments of yellowish quartzite and gray schist whose places of origin have been located on the long northern spur of Mount Clark.
