The Manitoba Escarpment (known in the United States as the Pembina Escarpment) is a scarp that marks the boundary of glacial Lake Agassiz. It occurs in South Dakota North Dakota and Manitoba. Originally formed by the undercutting of Cretaceous sandstones by the ancestral Red River the escarpment was later steepened by glacial scouring. The vista today of wooded hills with small farms tucked into valleys (such as the Pembina Valley) is reminiscent of pastoral sections of New England.
