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...

This 1:500,000 scale map of Wisconsin depicts sediment deposited by glaciers, streams, wind, and other processes during the Quaternary Period (2.58 million years ago to present). The map was made by compiling detailed Quaternary mapping and lithostratigraphic studies previously conducted by the WGNHS to generate consistent statewide Quaternary map units....
