Photograph of a view of the Three Brothers Mountain from the Merced River in Yosemite National Park, Mariposa County, California, ca.1900-1940. The triple rock formation forms part of the mountain range. Its mirrored image is visible in the river (foreground). Tall trees cover the area between the mountain range and the river.; "Yosemite Valley, about 3,000 feet deep and just a mile or two wide, is known for its landmark rock formations. Half Dome is perhaps the most recognized symbol of Yosemite. Rising over 4,000 feet above the Valley floor, it is one of the most sought-after landmarks in Yosemite. Some people even hike or rock climb to the top! El Capitan is a favorite for experienced rock climbers. Rising almost 3,000 feet above the Valley floor, it is the largest monolith of granite in the world. Cathedral Rocks and Spires form the eastern side of the canyon through which Bridalveil Creek flows. The Three Brothers are located just east of El Capitan. Sentinel Rock, like a sentry, overlooks Yosemite Valley, along the opposite side of the Valley From Yosemite Falls." -- unknown author.
