Cuesta

At that point the cuesta is 10 miles wide but the hilltops have an eastward descent of only about 62 feet. In its general eastward slope the surface of the cuesta is exactly that of one made by weathering and stream erosion, acting upon a gently-dipping limestone bed in a region never glaciated.

In eastern Wisconsin the cuesta is drift-covered and less noticeable; permanent settlement came later; lead and zinc mining was absent; and industrial development took a different course.
