There are four mountain ranges in the Canadian Columbia Basin.
The Monashees are bounded on the east by Columbia River and the Arrow Lakes and on the west by North Thompson River and the Interior Plateau. The highest peak is Hallam Peak (3,205 m), located northwest of Mica Creek.
The Selkirks are bounded on the west, northeast and north by the Columbia River and on the east by the Purcell Trench, Beaver River, Duncan River and Kootenay Lake. The highest peak is Mount Sir Sanford (3,519 m), located north of Rogers Pass and west of Kinbasket Reservoir.
The Purcells are bounded on the west by Kootenay Lake and Duncan River and on the east by the Rocky Mountain Trench. Many peaks are over 3,000 metres and contain spectacular formations, like the Bugaboos. The highest peak is Mount Farnham (3,493 m), located northeast of Panorama Resort near Invermere.
The Rockies stretch more than 4,800 km from northern BC to New Mexico. The highest peak is Mount Robson (3,954 m), near Valemount. Another notable peak is Snow Dome (3,456 m), which is on the Continental Divide. This means the snow that falls on Snow Dome may melt and flow into three different oceans: the Pacific, Arctic and Atlantic.
