Introduction: The Driftless Edge of the Midwest
Leaving Milwaukee, I-94 west merges into I-39/90 south, a corridor that traces the ancient edge of the Wisconsin Driftless Area—a region never flattened by Pleistocene glaciers. The road climbs gently near Janesville, where Cambrian sandstone bluffs begin to appear, remnants of a 500-million-year-old sea. This drive from Wisconsin’s industrial shoreline to Iowa’s literary capital covers about 185 miles, typically taking 3.5 hours without stops. But the real journey is in the quiet between exits.
