YOSEMITE FALLS

falls in Yosemite National Park, central California, U.S., near Yosemite Village, formed by creeks tumbling into the Yosemite Valley over the edges of hanging tributary valleys. The Upper Yosemite Fall drops 1,430 ft (436 m), the Lower 320 ft. With the cascades between, the total drop from the crest of the Upper to the base of the Lower is 2,425 ft, creating one of the world's highest cataracts. Maximum flow is reached in May and June; it diminishes greatly in years of little rainfall.
