Estimate the minimum thickness of the ice at the terminal moraine in the area of Blue Spring Lake. Assume that the ice extended up at least to the highest point on the moraine. (Determine the thickness of the ice, not its elevation.)
The question is based on Map T-11, the “Whitewater, Wisconsin” quadrangle (scale 1:62,500; contour interval 20 feet; dotted lines represent 10-foot contours). The irregular high ground of “Kettle Moraine State Forest,” running diagonally from the lower left to the right center of the map, is a terminal moraine left by a Pleistocene ice sheet (42°51'34"N, 88°35'59"W). The region northwest of the terminal moraine was once covered by the ice. The region in the southeast corner of the map is the edge of the glacial outwash plain. What will be an ideal response?
