Devils Lake study region, northeastern North Dakota. The basins of Devils Lake represent source depressions for material thrust into the ice-shoved hills (Sullys Hill, Crow Hill). Geomorphic features interpretated from Landsat MSS images, topographic maps, and ground observations. Position of lake shore based on 1988 images; ice margin positions based on Clayton et al. (1980, fig. 32). Study area orientation diverges about 10° from north due to path of satellite orbit. T.L. = Twin Lakes; D.L.M. = Devils Lake Mountain.
