The Sawtooth is a jagged arête joining Mount Bierstadt to (eventually) Mount Evans 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 above Guanella Pass. The northeast end of the sawtooth joins directly to the shoulder of Mount Spalding, from which a second (and slightly less abrupt) arête leads southeast to Mount Evans.
