Turtle Mountains
The Turtle Mountains make up the third section of the Drift Prairies. The mountain range consists of glaciated hills, extending four hundred feet above the level of the surrounding terrain. They were once part of the Missouri Plateau, and their top and that of the Missouri Plateau are at about the same elevation. The makeup of their layers is also the same as that of the Missouri Plateau. The Turtle Mountains were separated from the Missouri Plateau when the Souris (Mouse) River washed away all of the connecting materials, leaving the Turtle Mountains standing alone, separated by fifty miles. When the glaciers came, they smoothed them out, depositing a layer of drift, consisting mostly of sand and gravel.

The Turtle Mountains were so named because the Indians thought they looked like a turtle from a distance. They are heavily wooded, with several lakes, including Lake Metigoshe and Lake Upsilon, which are fresh-water lakes. The Turtle Mountains extend about forty miles from east to west, and about thirty miles from north to south. They extend into Canada.
