Columbia Mountains

The Columbia Mountains are a major mountain system in southeastern British Columbia, Canada, situated west of the Rocky Mountains and comprising several distinct subranges including the Selkirk, Purcell, Monashee and Cariboo ranges.

The region offers technical alpine climbing, glacier travel, backcountry skiing and long-distance hiking across varied terrain from forested valleys to steep, glaciated peaks. Recreational infrastructure and access points vary widely across the system; some valleys host well-known ski and outdoor-recreation centres while much of the area remains remote wilderness.

The ranges are part of a complex geological province distinct from the Rockies, with a long history of exploration, industrial forestry and hydroelectric development in river valleys. Mountaineering in the Selkirks and Purcells expanded in the late 19th and 20th centuries.

The system extends across southeastern British Columbia and spills into adjacent U.S. states to the south, forming a major topographic feature west of the Rocky Mountain Trench.

• Highest peak: Mount Sir Sandford is the highest peak in the system at 3,519 metres and is a key objective for mountaineers in the Selkirk Range.
