Abstract

One of the oldest mining districts in the United States, and one from which lead and zinc ores were mined in substantial quantity during the last five years or so is situated in the upper area of drainage of the Mississippi River. The district lies in the geologic province that has been known for several decades as the "Driftless Area," and is characterized by gently-rolling topography, which extends from the nearly-level uplands to the well-dissected areas bordering the major rivers. The Mississippi on the west, the Wisconsin River on the north, and the Rock River on the east virtually bound the district. The area of major mining activity includes roughly some 2500 square miles, most of which lies in Wisconsin. The land is fairly well wooded, particularly where greatly dissected, while the uplands and bottomlands contain acreage valuable for farming. The district is characterized by dairy farms and industries based upon dairy products. The area involved has a temperate climate with moderate precipitation. Its secondary roads are well kept, the road metal being both from tailings piles of mining operations as well as from quarries.
