Refer to the Map $3.3 .$ The following topographic map shows an interesting and informative geological feature called a drumlin, which is a pile of sediment left behind by a retreating glacier. Drumlins can be used to determine the direction of movement in the glacier with the glacier moving toward the shallower side of the structure. Using your previous answers for Map $3.3$, what direction was the glacier traveling? Note: unless indicated otherwise, assume that North is up (towards the top of the map).

Key Concepts

Glacial Movement

Glacial movement is a key concept in understanding how glaciers interact with the landscape. The morphology of sedimentary features like drumlins indicates the direction of ice flow, as glaciers tend to move toward the area with less sediment accumulation (the shallower side of the drumlin). This relationship helps geologists reconstruct past glacier movements and dynamics.

Topographic Map Analysis

Topographic map analysis involves reading contour lines and other map features to interpret landforms. In the context of glacial geology, analyzing the shape and orientation of features such as drumlins on a topographic map can reveal the direction of glacier movement and the processes that shaped the landscape.

Drumlins

Drumlins are streamlined hills composed of glacial till that have been shaped and deposited by moving glaciers. Their asymmetrical form—characterized by a gentle slope on the side from which the ice advanced and a steeper slope on the trailing side—provides clues about the flow direction of the glacier responsible for their formation.
