outlet glacier of Hofsjökull in Iceland exposed a drumlin field with more than 50 drumlins ranging from 90 to(-) 320 m in length, 30 to(-) 105 m in width, and 5 to(-) 10 m in height. These formed through a progression of subglacial depositional and erosional processes, with each horizontal till bed within the drumlin created by an individual surge of the glacier. The above theory for the formation of these Icelandic drumlins best explains one type of drumlin. However, it does not provide a unifying explanation
