The Sawtooth

The Sawtooth is a jagged arête joining Mount Bierstadt to Mount Blue Sky in the Front Range of central Colorado. The three points along this arête resemble the teeth of a saw, leading to its name. The southeast wall of the arête is the head of the cirque above Abyss Lake, while its northwest wall is the cirque at the head of a valley near the summit of Guanella Pass. The northeast end of the sawtooth joins directly to the shoulder of Mount Spalding, from which a second arête leads southeast to Mount Blue Sky. This second arête divides the glacial valley of Abyss Lake to the southwest from the cirque of Summit Lake to the northeast.
