Pleistocene geology of Kewaunee County, Wisconsin
Image of Kewaunee map and bulletin

Kewaunee County, at the southern end of the Door Peninsula, was overrun by glaciers many times. In this new bulletin, author Lee Clayton describes the county's complex glacial geology, from the surface soil down to solid rock. The accompanying map shows the placement of glacial sediments as well as glacial and post-glacial stream and lake sediments. [Bulletin 104]

Bulletin: $30.00 (plus shipping and handling), includes folded copy of the map

Frac sand in Wisconsin

frac sand in Wisconsin factsheet

The state's golden sands have inspired Wisconsin's version of a gold rush. This 2-page fact sheet shows where sandstone formations occur in Wisconsin, where frac sand is being mined and processed (as of October 2013), why our sand is so popular, and how it's being used.

Age and correlation of Silurian rocks in Sheboygan, Wisconsin, using integrated stable carbon isotope stratigraphy and facies analysis (Geoscience Wisconsin, vol. 21, part 2)

front page of Age and Correlation of Silurian Rocks

The exact age of Silurian rocks in eastern Wisconsin is uncertain due to a scarcity of outcrops, poor biostratigraphic control, and prominent facies changes. Using carbon isotope analysis, authors Patrick I. McLaughlin, Donald G. Mikulic, and Joanne Kluessendorf constructed a composite section from cores taken around the city of Sheboygan. Their work, detailed here, provides a preliminary revision to the age of Silurian rocks from +/– 2 million years to approximately 100,000 years. [GS21-a02] PDF

Municipal drinking water safety: The link between groundwater, pathogens, and public health

Most of us take for granted that our drinking water is safe. But 60 Wisconsin communities (with populations as high as 8,400) risk ongoing illness in children and the elderly from viruses and other pathogens in unsanitized water supply systems.

Municipal Drinking Water Safety, a new publication by the Wisconsin Geological and Natural History Survey and the Solid and Hazardous Waste Education Center, describes the link between illness and municipal drinking water supplies that are not disinfected.
