The Rocky Mountains generally feature an alpine climate, characterized by cold temperatures, significant snowfall, and high altitudes.

As elevation increases, temperatures drop, resulting in cooler conditions and distinct seasonal variations. In the alpine zone, temperatures can be quite low, even in summer, and snowfall can be substantial during winter months. This climate supports unique ecosystems, including alpine tundra, which hosts specialized vegetation and wildlife adapted to harsh conditions. The diverse microclimates within the Rockies also contribute to a wide range of habitats, making the region ecologically rich and varied.
