Nevada Fall is one of the major waterfalls in Yosemite National Park. With its 594-foot drop, it is almost twice as tall as nearby Vernal Fall. Because Nevada Fall is also fed by the Merced River, it flows year-round and in the spring contains a huge volume of water. Many of Yosemite's waterfalls dry up in late summer but not Vernal and Nevada Falls. You can always count on a good show from Nevada Fall no matter what time of year. The waterfall starts off fairly narrow at the top but spreads out to a wide curtain of water as it descends the cliff face.
