mammillated topography Hill relief with a streamlined, rounded, and smoothed appearance, normally resulting from the scouring action of an ice sheet, as in the Adirondack Mountains, eastern USA. However, some crystalline rocks may support a pseudo-mammillated surface formed by non-glacial processes, as on Ben Lomond, Tasmania.
