Sandpot

The Sandpot file contains information about silica sand potential. Specifically, this map unit shows those places where silica sand (see Explanation of terms, Plate III )occurs in the bedrock within 50 feet of the surface. The data layers from the references cited below were clipped to identify the condition of the commodity 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 sources of this information are:
