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. http://www.sentex.net/~tcc/sgfcrit.htmlFrom Atomica: [From drum, ridge, from Irish Gaelic druim, back, ridge, from Old Irish.]

Here's another geology glacier site, with diagrams of drumlins. Scroll down about halfway until you see caption "Drumlins" and then see "Diagrams 1 and 2..." Note that they are egg shaped, with long axis parallel to direction of ice flow. http://math.cochise.edu/People/faculty/wellerr/chapter12.html
