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 in length, it was extensively sculpted by glaciers in previous ice ages.
Lamoille Canyon begins at Liberty Peak at an elevation of 11,032 ft . It quickly descends to a glacial basin now occupied by Lamoille Lake. A nearby granite shelf contains the picturesque Dollar Lakes. Further down the canyon is a large stand of Whitebark pine and the Road's End Trailhead, the high point (8,800 ft.) of Lamoille Canyon Road, which is a National Forest Scenic Byway. This is also the northern terminus of the 38-mile Ruby Crest National Recreation Trail, and the start of the much shorter trail to Island Lake.
Road's End is where Lamoille Canyon begins a sweeping turn around the flanks of Thomas Peak, 11,325 ft . The glaciers have deeply carved the canyon, leaving a classic U-shaped cross section and, high on the side of Thomas Peak, four hanging valleys (including Island Lake). The road then passes the Terraces Picnic Area (featuring more glacial remnants) and Verdi Peak. A nearby nature trail exhibits the diverse plant life in the canyon bottom.(Wikipedia)
