From Wikipedia (Modified): Bridalveil Falls is one of the most prominent waterfalls in the Yosemite Valley, Yosemite National Park in California. The Ahwahneechee indian tribe believed that Bridalveil Fall was home to a vengeful spirit named Pohono which guarded the entrance to the valley, and that those leaving the valley must not look directly into the waterfall lest they be cursed. They also believed that inhaling the mist of Bridalveil Fall would improve one's chances of marriage. Bridalveil Falls is a 617 ft drop and flows year round. The glaciers that carved Yosemite Valley left many hanging valleys which spawned the waterfalls that pour into the valley. All of the waterways that fed these falls carved the hanging valleys into steep cascades with the exception of Bridalveil Fall. Bridalveil still leaps into the valley from the edge of the precipice, although that edge has moved back into an alcove from the original edge of the valley. The primary source of Bridalveil Falls is Ostrander Lake, some 9.9 miles to the south. When the wind blows briskly, the waterfall will appear to be falling sideways. During lesser water flow, the falls often don't reach the ground. Because of this, the Ahwahneechee Native Americans called this waterfall Pohono, which means Spirit of the Puffing Wind.
