Lamoille Canyon is the largest valley in the Ruby Mountains, located in the central portion of Elko County in the northeastern section of the state of Nevada, in the western United States. Approximately 12 miles (19Â km) in length, it was extensively sculpted by glaciers in previous ice ages.
Lamoille Canyon begins at Liberty Peak at an elevation of 11,032Â ft (3,363Â m). It quickly descends to a glacial basin now occupied by Lamoille Lake. A nearby granite shelf contains the Dollar Lakes. Further down the canyon is a large stand of Whitebark pine and the Road's End Trailhead, the high point (8,800Â ft (2,700Â m)) of Lamoille Canyon Road, which is a National Forest Scenic Byway. This is also the northern terminus of the 38-mile (61Â km) Ruby Crest National Recreation Trail, and the start of the much shorter trail to Island Lake.
