TitleYosemite Falls
DescriptionYosemite Falls is one of several spectacular and well known waterfalls in Yosemite Valley National Park. The falls, fed by snowmelt from the high Sierra peaks, exist because glacial erosion has carved Yosemite Valley into a smooth deep valley. Yosemite Falls is a composite waterfall totaling 746 meters (2,425 ft), with the Upper Fall (435 m; 1,430 ft), Middle Cascades (208 m; 675 ft), and Lower Fall (98 m; 320 ft). The steps result from the horizontal jointing patterns in the rock, which is composed of Sentinel Granodiorite. It is the fifth highest waterfall in the world, behind Angel Falls in Venezuela (988 m; 3,212 ft) and others in Norway and South Africa.
