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.
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.
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 .
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".

A geologic map of Yosemite National Park Kuna Crest Granodiorite (also called Granodiorite of Glen Aulin ), [ 1 ] is found, in Yosemite National Park , United States. The granodiorite forms part of the Tuolumne Intrusive Suite (aka Tuolumne Batholith ), one of the four major intrusive suites within the Sierra Nevada .
Johnson Granite Porphyry is found in Tuolumne Meadows, Yosemite National Park. Johnson Granite Porphyry was named for Johnson Peak, the highest mountain in Tuolumne Meadows, Yosemite National Park. [1] Its area is estimated at 1,100 square kilometres (420 sq mi), the exposed area covering roughly 40 square kilometres (15 sq mi). [2]
The Tuolumne Intrusive Suite is the youngest and most extensive of the intrusive suites of Yosemite National Park, and also comprises about 1/3 of the park's area. The Suite includes Half Dome Granodiorite, Cathedral Peak Granite, and Kuna Crest Granodiorite.
