Outlines the physiographic history of southwestern North Dakota; describes terraces and terrace gravels along Cannonball River, particularly in regard to pebbles of material not now found in the drainage basin of the stream; and suggests the existence in the area of an easterward dipping upland surface with possible continuations eastward and westward upon which the present streams, notably Missouri and Little Missouri, have anomalous courses.
