Yosemite Valley is a census-designated place in Mariposa County, California, United States. It consists of the developed area of Yosemite Village and the other areas of the Yosemite Valley in Yosemite National Park. The population was 1,035 at the 2010 census, up from 265 at the 2000 census.
Almost all of the landforms in the Yosemite area are cut from the granitic rock of the Sierra Nevada Batholith (a batholith is a large mass of intrusive igneous rock that formed deep below the surface). About five percent of the park's landforms (mostly in its eastern margin near Mount Dana) are metamorphosed volcanic and sedimentary rocks.
The Yosemite Valley itself was discovered by European American settlers in 1851. There are earlier instances of other travelers entering the Valley but James D. Savage is accredited with discovering the area that is now known as Yosemite National Park.
Bass Lake is situated in the Sierra National Forest approximately 14 mi from the south entrance of Yosemite National Park. Established in 1895 as "Bass Lake Village", the community grew up around the newly created Bass Lake reservoir that supplied the first hydroelectric generating project in Central California. Much of the community and the reservoir is devoted to the tourism industry.
