This means about $300 for each farmer in the glaciated area. * R. H. Whitbeck, "Economic Aspects of Glaciation in Wisconsin", in "Annals of the Association of American Geographers," vol. III in , pp. 62-67. Wisconsin is by no means unique. In Ohio, for instance, there is also a driftless area. * It lies in the southeast along the Ohio River.
The result of this erosion and transportation has been to change the conditions of the surface both as regards soil and drainage. As the reader has doubtless perceived, ordinary soil is, outside of the river valleys, derived from the rock beneath where it lies. In glaciated districts the material is commonly brought from a considerable distance, often from miles away.
Within the limits of the glaciated area it covers the country without regard to the relief, mantling with its debris not only lowlands and valleys but also highlands and mountain slopes. The boundary of the drift is equally independent of the relief of the land, crossing hills and plains impartially, unlike water-laid deposits, whose margins, unless subsequently deformed, are horizontal.
Upwards of 10,000,000 acres of glaciated land have already been developed in the most populous parts of the State. If the average value of all products on this area is reckoned at $15 per acre and if the increased value of agricultural products due to glaciation amounts to 30 per cent, then the net value of glaciation per year to the farmers of Wisconsin is $45,000,000.
Marine stratified loam, lowest member of glacial formation. 3. Blue clay or till, with erratic blocks unstratified. 4. Yellow sandy till, with pebbles and glaciated boulders. 5.
