Limits To Ice Thickness In Iowa During The Late Wisconsinan, Eric C. Brevik
Limits To Ice Thickness In Iowa During The Late Wisconsinan, Eric C. Brevik
Journal of the Iowa Academy of Science: JIAS
Minimum and maximum limits to Des Moines Lobe ice thickness in Iowa during the Late Wisconsinan glaciation are calculated. These limits are based on minimum and maximum ice thickness calculations for the Des Moines Lobe in eastern North Dakota using crustal depression indicated by Lake Agassiz strandlines. Minimum and maximum basal shear stresses for the Des Moines Lobe are calculated by projecting a flow line from the terminus of the Des Moines Lobe back up-ice to the study site in northeastern North Dakota. Ice thickness in Iowa is then calculated with a method that uses the basal shear stress values. …
