Type of Moraine | Location with Respect to Ice Front | Comments |
---|
End moraine | At ice front | After glacier melts, seen as ridge parallel to former ice front |
Terminal moraine | At ice front marking farthest advance of ice | Type of end moraine |
Lateral moraine | Along edge of glacier where it scrapes side walls of valley | Heavy sediment load eroded from valley walls; when ice melts, seen as ridge parallel to valley walls |
Medial moraine | Formed as two joined glaciers merge their lateral moraines below junction | Inherits its sediment load from lateral moraines that formed it; forms ridge parallel to valley walls |
Ground moraine | Beneath the ice as a layer of glacial debris | Ranges from thin and patchy to a thick blanket of tills |
