Boulder Mountains

The Boulder Mountains are a remote and rugged mountain range located in southwestern Montana. Spanning over 30 miles, the range is characterized by steep, jagged peaks, deep glacial valleys, and alpine meadows. The terrain is challenging, with significant elevation gain and exposed rocky sections. The mountains were shaped by glacial activity during the last ice age, leaving behind dramatic cirques, arêtes, and U-shaped valleys. Forests of pine, fir, and aspen cover the lower slopes, transitioning to alpine tundra near the summits.
