Yosemite Falls from Housekeeping Camp Beach. Yosemite Falls is the highest measured waterfall in North America. Located in Yosemite National Park in the Sierra Nevada of California, it is a major attraction in the park, especially in late spring when the water flow is at its peak. The total 2,425 feet (739 m) from the top of the upper falls to the base of the lower falls[1] qualifies Yosemite Falls as the sixth highest waterfall in the world, though with the recent discovery of Gocta Cataracts, it appears on some lists as seventh. The Ahwahneechee people of Yosemite Valley called the waterfall “Cholock” and believed that the plunge pool at its base was inhabited by the spirits of several witches, called the Poloti.[3][4] An Ahwaneechee folktale describes a woman going to fetch a pail of water from the pool, and drawing it out full of snakes. Later that night, after the woman had trespassed into their territory, the spirits caused the woman's house to be sucked into the pool by a powerful wind, taking the woman and her newborn baby with it. http://en.wikipedia.org/wiki/Yosemite_Falls
