Unravelling climatic fluctuations during the Pleistocene is crucial to our understanding of present climate and future predictions. One of the most prevalent relics of Pleistocene ice sheets are drumlins, yet their mapping has considered almost exclusively their width and length, as an indication of relative ice velocity during formation. The third dimension, including drumlin relief and volume has largely been ignored. This study uses Digital Surface Models (DSM) from the Shuttle Radar Topography Mission (SRTM) for three-dimensional mapping of a large sample of the Livingstone Lake Drumlin Field in Canada. Analysis of this sample reveals a strong linear relationship between observed drumlin volumes and the volumes of an ellipsoid based on width, length and relief.
