Looking at Canada's Interior Plains

Alberta, Saskatchewan, B.C., N.W.T., Manitoba, Yukon

Locations of the Region

The interior plain (red) is located mostly in Alberta and stretches across Saskatchewan, British Colombia, North West Territories, Manitoba, and a small part of Yukon. Interior plains usually have rolling hills and deep, wide river valleys.

Fun Facts: How the Region was Formed

Inland seas covered the region. As that was happening, eroded sediments from the Canadian Shield and Rocky Mountains were deposited into these seas over millions of years. Then these sediments were compressed into sedimentary rock slowly creating Interior Plains.
