I found a word that I just love: drumlins!
The proposed catastrophic sheet floods, as wide as the drumlin fields, formed the drumlins and related streamlined landforms, such as flutings, over wide areas. So-called rogen moraine, consisting of transverse ridges of drift, often found associated with drumlins, is reinterpreted in the meltwater flood hypothesis as possible giant current ripples.
