The Missouri Plateau and Drift Prairie

To the west of the Red River Valley is the Drift Prairie and the Missouri Plateau (or Missouri Coteau). The Drift Prairie is bordered on the north by the Turtle Mountains and separated from the Red River Valley by the Pembina Hills. This area rises from 200 to 2,000 feet over the Red River Valley. The Drift Prairie is covered in lakes, stream valleys, and rolling hills. This region suffers moderate to severe flooding from the Red River almost annually, caused by the heavy snowfall in this region every winter.

The Great Plains

About half of North Dakota is covered by the Great Plains. The Great Plains, in the southwestern section of the state, are hilly and rich in mineral deposits. This area rises about 300 to 400 feet above the Drift Prairie east of the Missouri River. Along the Missouri River, the land is lower. This area is called the Missouri Break. To the south and west of the river is an area of rugged valleys and buttes called the Slope.

The Badlands

The Badlands lie in southwestern North Dakota. The Badlands are exposed surfaces of stone and clay that

In some areas of the Badlands the rocks contain lignite coal that has been burning for many years. The clay above these coal beds has turned bright pink and red. White Butte, the highest point in North Dakota, is located in the Badlands, and stands 3506 feet (1069 m) above sea level.
