Compare the dimensions of three of the drumlins on the map, identified below by their peak elevation marked with an x. These drumlins are found from bottom center to upper right on the map. “Drumlin Height” refers to the relief of the drumlin, not its elevation. Estimate the “length” of the drumlins from north to south (a graphic map scale is found inside the front cover of the Lab Manual). Finally, note whether the north-facing or southfacing side of the drumlin has the steepest slope.
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.
