CS_Pot

The CS_Pot file contains information about silica sand and limestone (see Explanation of terms, Plate III) potential. Specifically, this map unit shows only those places where both commodities occur within 50 feet of the surface, one layer on top of the other. The data layers from the references cited below were modified to identify the above condition of both commodities occurring within 50 feet of the surface. The silica sand information contains data for both sandstone formations - the Ordovician St. Peter Sandstone, near the city of St. Peter, and the Cambrian Jordan Sandstone for all the remaining area. The limestone information contains data for the Prairie du Chien group. The sources of this information are:
