Ribbon Fall

Cataract on the west slope of the Sierra Nevada in Yosemite National Park, east-central California, U.S. With a drop of 1,612 feet (491 m), it is one of the world's highest waterfalls and one of the park's most scenic features. Reaching a peak volume during May and June, it is fed mainly by melting snow; hence, it is sometimes dry for part of the year.
