Among the earliest candidates for National Park status, Yosemite features towering granite cliffs, dramatic waterfalls, and old-growth forests at a unique intersection of geology and hydrology. Half Domeand El Capitan rise from the park's centerpiece, the glacier-carvedYosemite Valley, and from its vertical walls drop Yosemite Falls, North America's tallest waterfall. Three giant sequoia groves, along with a pristine wilderness in the heart of the Sierra Nevada, are home to an abundance of rare plant and animal species.
