Fjords in Canada, (fiords in Canada), are long, narrow inlets characterized by steep sides, created in a valley carved by glacial activity. A fjord can have two or more basins separated by sills. The bowls can have a depth of 20 to 500 m (66 to 1,640 ft) and the dividing sills can raise up to a few metres below the water surface. Mountainous glaciated areas in Canada are along the British Columbia Coast: from the Alaskan border along the Portland Canal to Indian Arm.
