These poorly drained soils form in alluvium overlying glacial till in upland depressions and wide drainageways. Permeability is slow, and water ponds on the surface after heavy rains and snow melt. Soils typically are wet except in late summer and fall unless they have been drained.

Tetonka soils have a clayey Bt horizon that is overlain by a white albic E horizon. Where drained, these soils are commonly used for cultivated crops, including corn, soybeans, small grains, and sorghum. Mean annual precipitation ranges from 17-26".Scale is in feet.
