Depth to Silurian Bedrock in Eastern Wisconsin
Silurian-aged bedrock in eastern Wisconsin is shallow, fractured, and contains groundwater that is susceptible to surface water contamination. Revisions to Wisconsin state rules ATCP50 and NR151 to regulate manure spreading over this Silurian-aged bedrock create the need for a depth-to-bedrock map of eastern WI. The Wisconsin Geological and Natural...-

Elevation contours of the Precambrian surface of south-central Wisconsin
Elevation contour data and an accompanying report provide an updated interpretation of the elevation of the top of Precambrian bedrock in south-central Wisconsin. The elevation surface was developed from geologic and geophysical data, and provides new detail on the entrenched bedrock valleys that were incised into the north and south ranges of the Baraboo...-

Quaternary Geology of Calumet and Manitowoc Counties, Wisconsin
All of what is now Calumet and Manitowoc Counties was covered by ice during the last great glaciation, between 30,000 and 11,000 years ago. This bulletin explains the glacial history, interprets the deposits left behind, and portrays the distribution of the deposits on a map and cross sections. This report should be useful to planners and development...-
