Matterhorn Peak is located in the Sierra Nevada, in the western U.S. state of California, at the northern boundary of Yosemite National Park. At 12,285 feet (3,744 m) elevation, it is the tallest peak in the craggy Alps-like Sawtooth Ridge and the northernmost 12,000-foot (3,700 m) peak in the Sierra Nevada. The peak also supports the Sierra's northernmost glacier system.
