Canadian Rocky Mountains Landforms

The Canadian Rocky Mountains are part of the vast Rocky Mountain range that spreads across the North American continent. Much of the ecoregion is mountainous, reaching more than 7,000 feet, while the Pend Oreille and Columbia River valleys lie at roughly 1,300 feet above sea level.

Washington’s Canadian Rocky Mountain ecoregion is a landscape shaped by ice. Retreating glaciers left behind broad horseshoe-shaped valleys and craggy mountain peaks.

The north-flowing Pend Oreille River cuts a diagonal line through the ecoregion, meeting the Columbia River at the Canadian border. The Columbia River flows south from Canada, crossing the Canadian Rocky Mountains ecoregion at its northwest corner.
