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.[1]
The largest pluton of the Tuolumne Intrusive Suite is Cathedral Peak Granodiorite, which extends long distances both the north and south of Tuolumne Meadows.[2] The southwestern part of the Tuolumne Intrusive Suite is made up of Half Dome Granodiorite.[2] The youngest, smallest, and most central rock body is of the Johnson Granite Porphyry[2]
