lateral moraine
moraine that forms along the side of a glacier
medial moraine
moraine that forms where two glaciers come together
terminal moraine
moraine that forms at the snout of a glacier
ground moraine
unsorted material left beneath a glacier when the ice melts
Drumlins

how long, high and wide are drumlins?
1.5km long, 50m high, 500m wide
erratics
