The topography of the Driftless Area, which was never glaciated during the Quaternary Period, is dominated by fluvial incision into flat-lying Paleozoic bedrock, resulting in deep, dendritic valleys. Local relief reaches 115 meters. Sediment coring across the region reveals that the geology of unconsolidated surficial materials is often controlled by the...

The Quaternary geologic map of Waupaca County, Wisconsin, provides details about the surficial sediment and landscapes that were formed underneath and adjacent to the Laurentide Ice Sheet during the late Wisconsin Glaciation (ca. 20,000 years before present). These landscapes include lowlands underlain by glacial and postglacial lake sediment, uplands...

Dodge County lies in southeast Wisconsin, an area almost entirely covered by glacial deposits. This map interprets the distribution of the buried bedrock units across the county. Geologist Esther Stewart’s refinement of the bedrock elevation contours may help land-use planners identify areas most susceptible to groundwater contamination from applications...

Located in southeast Wisconsin, Jefferson County is almost entirely blanketed by sediments that were delivered or shaped by the ice sheet that covered this area during the last ice age. New mapping interprets the distribution of the bedrock surface that is buried beneath those glacial sediments as interpreted by three drill cores, over 13,000 well...
