Description: A map from 1911 from the Baldwinsville quadrangle showing the topographic feature of roc drumlins or drumloids. The drumlin-shaped forms in the upper part are developed on shale. Roc drumlins are distinct from the more common type of drumlin in that they are due to erosion rather than the typical up–building.
