Most geomorphologists suggest that the long axis of a drumlin reflects the direction of ice flow, with the steepest end facing the direction from which the ice came. Based on this assumption, from which direction did the ice flow over this region?
The question is based on Map T-12, the “Sodus, New York” quadrangle (scale 1:24,000; contour interval 10 feet) and Figure 47-3, a stereogram of this same area (43°09'55"N, 77°04'51"W). The map and stereogram show a number of drumlins, each with its long axis oriented approximately north-south.
What will be an ideal response?
From north to south
