Modifying this is the influence of the water in Lake Superior and Lake Michigan. Wisconsin lies in the belt of prevailing westerly winds. Applied Climatology. The important points about the Wisconsin precipitation are (1) that the region is humid and has the topographic development characteristic of a humid region.

The magnetites associated with the basal gabbros of the Lake Superior Keweenawan are in purely .
