Mount Dana is a mountain in the U.S. state of California. Its summit marks the eastern boundary of Yosemite National Park and the western boundary of the Ansel Adams Wilderness. At an elevation of 13,061 feet (3,981 m), it is the second highest mountain in Yosemite (after Mount Lyell), and the northernmost summit in the Sierra Nevada which is over 13,000 feet (3,962.4 m) in elevation. Mount Dana is the highest peak in Yosemite that accessible to summit. The mountain is named in honor of James Dwight Dana, who was a professor of natural history and geology at Yale.
Mount Dana is composed of prebatholithic rock that is mostly reddish metamorphic rock, which was composed by metavolcanics of surfacing magma from the Mesozoic Era.
Mount Dana's northern face includes a small, receding glacier known as the Dana Glacier. The Dana Meadows lie at the foot of the mountain. From the top, lakes throughout Dana Meadows, Mono Lake, Tioga Peak and many other mountains are in view.
