Upper and Lower Yosemite Falls, Yosemite Valley, Yosemite National Park, California
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 fall to the base of the lower fall 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.
In years of little snow, the falls may actually cease flowing altogether in late summer or fall. A very small number of rock climbers have taken the opportunity to climb the normally inaccessible rock face beneath the falls, although this is an extraordinarily dangerous undertaking; a single afternoon thunderstorm could restart the falls, sweeping the climbers off the face.
Lower Yosemite Fall is easily accessible near the Yosemite Lodge in Yosemite Valley. The top of Upper Yosemite Fall may be reached via a steep, strenuous, and usually crowded 3.5 miles (5.6 km) hike beginning near Camp 4. The Upper Fall may also be reached via several routes from the Tioga Road to the north.
