Geologic Map of the Durwards Glen 7.5-Minute Quadrangle, Columbia and Sauk Counties, Wisconsin
The Durwards Glen 7.5-minute quadrangle map is located in Columbia and Sauk counties, southeast of the city of Baraboo. This geologic map includes Precambrian through Quaternary units. New mapping has focused on subdividing the Baraboo Quartzite into four separate members and delineating Quaternary deposits in greater detail than prior work.-

Geologic map of the Bloomington and Brodtville 7.5-minute quadrangles, Grant County, Wisconsin
The geologic map of the Bloomington and Brodtville quadrangles includes 1:24,000 scale mapping of both surficial and bedrock geology. There is little structural folding or faulting in this portion of the Driftless Area. Thus, it is ideal for studying the hydrostratigraphic framework of the mapped units. The accompanying report presents stratigraphic...-
