Conical shaped hills of sand and gravel (kames) represent features of stagnant ice. Most of them probably formed as sediment-laden meltwater, flowing across the surface of a mass of dead ice, passed into a hole through the ice. Sands and gravels (outwash) thus began to fill the hole. As the ice walls eventually melted away, the sediments were left behind as this landform. Because they are both landforms resulting from stagnating ice, kames, kettles, and eskers often occur on the same landscape.
The selection of this kame at Tower City, N.D., as the site for a cemetery was probably not made just out of esthetics. Instead, the well-drained soils of the kame would have also allowed for grave excavation well into the winter months.
