a large area of the west central US where the land is high and flat. It includes the 10 Plains States, stretching about 400 miles/644 kilometres east from the Rocky Mountains, and from Canada to southern Texas. It was the home of the Plains Indians and is also called the Wheat Belt of America, although dry weather in the 1930s turned the southern part into the Dust Bowl.
