Mount Walter is a 13,141-foot summit in northern New Mexico's Taos Mountains, within the Sangre de Cristo range and the Wheeler Peak Wilderness of Carson National Forest. It is the state's second-highest named summit, yet it is not usually considered a fully independent mountain. Its prominence is only about 53 feet above the saddle linking it to nearby Wheeler Peak, and it stands just 0.4 miles north-northeast of that higher summit. As a result, Mount Walter is closely associated with Wheeler Peak, New Mexico's highest point, as part of the same high ridge in the southern Rockies.
