NE.-trending drumlins and related streamline features of late Pleistocene age are found in the Warwick-Tokio area of the Devils Lake region of North Dakota. These features range from small drumlins to large ridges or "scorings" in end moraines. Some isolated end moraine patches contain exposures of Pierre shale bedrock of Cretaceous age. These bedrock "highs" seem to have controlled the location of the morainal patches but do not seem significant in the origin of the stream-line features. The origin of the streamline features is uncertain but they are probably erosional rather than depositional. Why they are localized in this part of the Devils Lake region and absent elsewhere is not clear. No significant differences of terrain or materials were found among the various parts of the region. Possibly some as yet unknown factor in the now vanished ice is responsible for their formation in this small area.
