Crag and Tails A crag-and-tail is an elongate hill or ridge characterized by two features at either end: at its stoss (up-ice) end is a steep knob of rock or ice-smoothed resistant bedrock that blocks glacier movement; and on its lee end there is an intact and less resistant tail protected by the crag itself – also referred to as drumlins. Crags are often formed by the powerful forces of nature, especially glaciers. v. , 2015 Crag and tails are elongated streamlined hills (Figure 7) that are the result of erosion by ice on their upflow end and preservation of existing sediment or bedrock, or deposition of sediment on their downflow end.
