TitleOdanah Member of the Pierre Formation in contact with the Niobrara Formation in North Dakota
DescriptionNear the top of the Pembina Escarpment is a good cut on the west side of the road that exposes shale. This light gray shale is the Odanah Member of the Pierre Formation. It is rather hard, with fine, indurated sand, and it forms the cap rock on the Pembina Escarpment so it is at least partially responsible for holding the escarpment up, making it more resistant to erosion.
