Yosemite Falls
Yosemite Falls is a waterfall in Yosemite National Park, California, formed by Upper Yosemite Fall, the Middle Cascades, and Lower Yosemite Fall.
Upper Yosemite Fall: The uppermost and tallest section of Yosemite Falls, dropping about 1,430 feet over a sheer granite cliff. It supplies the waterfall’s largest single drop and feeds the cascades below.
Snowmelt: Water released when accumulated snow melts, often feeding rivers and streams in spring. Melting Sierra Nevada snow drives Yosemite Falls’ strongest seasonal flow.
Yosemite Falls Trail: A strenuous hiking trail climbing from Yosemite Valley to the rim above Upper Yosemite Fall. It reaches viewpoints beside the upper drop and overlooks the valley.
Yosemite Firefall: A brief orange glow on Horsetail Fall in February, produced when sunset light aligns with the falling water. It is a separate Yosemite waterfall spectacle often compared with Yosemite Falls.
Middle Cascades: A steep, segmented series of cascades between Upper Yosemite Fall and Lower Yosemite Fall. These cascades connect the two major drops across Yosemite Falls’ longest section.
Sierra Nevada: A major mountain range in California and Nevada, containing Yosemite National Park. Snow from this range feeds Yosemite Creek and the waterfall.
Columbia Rock: A granite viewpoint along the lower portion of Yosemite Falls Trail, overlooking Yosemite Valley. It offers an early elevated view of the waterfall and valley.
John Muir: A Scottish-American naturalist and writer whose advocacy helped establish Yosemite National Park. His writing and conservation work helped make Yosemite’s landscapes nationally prominent.
Lower Yosemite Fall: The lowest section of Yosemite Falls, dropping about 320 feet into Yosemite Valley. It forms the waterfall’s visible base and is accessible from a short trail.
Orographic precipitation: Precipitation produced when moist air rises, cools, and condenses over elevated terrain. It helps supply the mountain snowpack that later feeds the falls.
