The product of 20 million years of geologic faulting, volcanic activity, and glaciation, the Wasatch Mountains, the western range of the Rocky Mountains, stretch across Utah from the Bear River in the north to Mount Nebo near Nephi in central part of the state. Most elevations along the range are generally between 9,000 and 10,000 feet; Mount Nebo is the highest peak at 11,877 feet. Some of the other significant peaks from north to south include Willard Peak, Mount Ogden, Bountiful Peak, Mount Olympus, Lone Peak, Mount Timpanogos, Provo Peak, Spanish Fork Peak, and Loafer Mountain.
Since the earliest days of Mormon settlement, the majority of Utah's population has chosen to settle along the range's western front, where numerous river drainages exit the mountains. The mountains were a vital source of water, timber, and granite for early settlers. Today they continue to serve as the primary source of water for the populous Wasatch Front, and to provide year-round recreational opportunities to residents and visitors alike.
