Mount Timpanogos is a dominant Wasatch Range peak in northern Utah, rising 11,752 feet and standing prominently above Utah Valley. Named for the Timpanogos people, who lived nearby from about AD 1400, it is notable for limestone and dolomite formed on an ancient seafloor roughly 300 million years ago, then uplifted and sculpted by glaciers and water into sharp ridges, cirques, and features such as Emerald Lake and the buried Timpanogos Glacier. The mountain also includes Timpanogos Cave National Monument and is one of Utah’s most popular climbing and hiking destinations. Its modern history includes the long-running “Timp Hike,” later ended after damage to the fragile alpine environment.
