Tower Mountain, elevation 13,558 ft (4,132 m), is a summit located northeast of Silverton, Colorado.

[2] Precipitation runoff from the mountain drains into tributaries of the Animas River.

Topographic relief is significant as the summit rises 3,750 feet (1,140 meters) above the Animas River in two miles (3.2 km).

According to the Köppen climate classification system, Tower Mountain is located in an alpine subarctic climate zone with long, cold, snowy winters, and cool to warm summers.
