 | | The tree-covered, grassy, or farmed slopes around the flanks of the Killdeer Mountains are underlain primarily by the Golden Valley Formation, a Paleocene to Eocene age rock unit. |
 | | They cover an area of about a thousand square miles, half in North Dakota, half in Manitoba and this, along with river bottom land and the forested Pembina Hills area to the east, is one of the few wooded areas in the region. |
 | | As sediment was eroded away, new hills and valleys were shaped and, gradually, as the sediments surrounding the Turtle Mountains were carried away to Hudson Bay, a large mesa was left standing where the Turtle Mountains are today. |
