Along the sandy beach of Terry Andrae State Park on Lake Michigan, Wisconsin, an inverse relationship exists between foreshore slope angle and mean grain size. Mean grain size decreases as the heavy mineral content increases. Grain size, wave steepness, and wave length have been reported as variables affecting the foreshore slope angle. It is here suggested that the heavy mineral content in the mid-foreshore be accepted as an active variable that influences the foreshore slope angle.
