TitleExfoliation of granodiorite in Yosemite National Park, USA
DescriptionThis is a photograph of exfoliation (peeling off of large sheets) on a granodiorite dome near Tanaya Lake in Tuolomne Meadows, Yosemite National Park, USA. This dome is part of the Sierra Nevada Batholith, a plutonic mass of rocks (mostly granodiorite) in eastern California and Nevada. The rocks of the batholith are Mesozoic, ranging in age from about 220 to 75 m.y. The batholith is actually composite, consisting of a large number of different plutons. Glacial action and exfoliation combined to produce many smooth rounded “domes” in Yosemite country.
