The beautiful Tuolumne River can be found in the state of California, in the United States, where it rises in central Sierra Nevada in Yosemite National Park, lovely flowing westward through the foothills to its confluence with the San Joaquin River in the Central Valley, near Modesto. Well, the section of the river beginning immediately below Tuolumne Meadows and finishing just shy of Hetch Hetchy Valley, which is famous as the Grand Canyon of the Tuolumne. Therefore, the riverbed forms a spectacular staircase through much of thirty-three miles, following in a series of striking waterfalls. Maybe the greatest of these is the 800-foot Waterwheel Falls, the largest waterfalls on the Tuolumne River. Well, at the Waterwheel Falls, the river dashes down a slanted surface and come into a series of small ledges initiating the water to deflect away from the rock surface in great arches, similar waterwheels. Moreover during the high-water season (in early summer), columns or waterwheels, of water can rise 15 to 20 feet high.
