Road's End is where Lamoille Canyon begins a sweeping turn around the flanks of Thomas Peak, . 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.
