Generalized geologic map of the Yosemite area. (Based on a USGS image) The exposed geology of the Yosemite area includes primarily granitic rocks with some older metamorphic rock. The first rocks were laid down in Precambrian times, when the area around Yosemite National Park was on the edge of a very young North American continent.
El Capitan Granite is a type of granite (also see granodiorite), in a large area near El Capitan, in Yosemite National Park, California, United States. The granite forms part of the Tuolumne Intrusive Suite (also known as Tuolumne Batholith), one of the four major intrusive suites within the Sierra Nevada .
Yosemite Valley represents only one percent of the park area, but it is where most visitors arrive and stay. More than half a dozen creeks tumble from hanging valleys at the top of granite cliffs that can rise 3,000–3,500 feet (910–1,070 m) above the valley floor, which itself is 4,000 ft (1,200 m) [ 3 ] above sea level .
Annual park visitation exceeds 3.5 million, with most visitor use concentrated in the seven-square-mile (18 km 2) area of Yosemite Valley. [1] The geography of the Yosemite area can be visualized with the clickable map, below: Painting of Yosemite by Heinrich C. Berann. Aerial view of the entire park from the west, looking east.
Half Dome Granodiorite dominates Yosemite Valley area east of Royal Arches and Glacier Point. At Church Bowl and in the cliff west of Royal Arches, horizontal dikes of Half Dome Granodiorite cut the older granodiorite of Kuna Crest. Half Dome Granodiorite forms the sheer cliffs to the north of the trail between the Ahwahnee Hotel and Mirror Lake.

Original notes that the data was "generalized from geological map of Yosemite National Park and vicinity (Huber and others, in press)" and that "an intrusive suite is a grouping of genetically related plutonic rocks".
