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 surficial geology and topography of the Driftless Area are thus distinct from the surrounding region where multiple phases of glaciation left their mark. This pamphlet, a collaborative effort between...
