What are examples of evidence from the midwest that there were large continetal ice sheets covering major parts of minnesota and wisconsin (as recently as 16,000 years ago)? Which are the correct ones? drumlins- streamlined hills that line up with the ice flow direction eskers- sinous narrow ridged of stratified (water laid) saind and gravel surrounded by areas of (glacial) till large end moraines that stretch for tens to hundreds of miles and mark the limits of the lobate shape of various glacial ice lobes that flowed over lower topographic areas at various times extensive flat plains underlain by clay or silt/clay laminations, which indicate the existence of large glacial lakes commonly adjacent to the ice lobe limits the wide. array of different rock types found all deposited as a jumbled mix, with some rocks clearly indicating their soure in nothernmost Minnesota, Wisconsin, or farther north in Canada. extensive pluvial lakes in former desert basins
