According to the Köppen climate classification system, Golden Horn is located in an alpine subarctic climate zone with long, cold, snowy winters, and cool to warm summers.[7] Due to its altitude, it receives precipitation all year, as snow in winter, and as thunderstorms in summer, with a dry period in late spring. Precipitation runoff from the mountain drains west into tributaries of the Dolores River, and east to the Animas River via Mineral Creek.
