Blue Mound, with an elevation of . The feature is located in Blue Mound State Park, in Iowa County. During the 19th and early 20th centuries, lead and zinc mining was a major industrial activity in the Driftless Area, drawing many foreign immigrants to settle in the region to work in the mines. Early miners often lived in the mine tunnels, leading outsiders to compare them to the burrowing badger; a nickname that eventually came to be used for all Wisconsin residents. An example of an early lead shot tower and smelting house is preserved in Tower Hill State Park. Due to the influx of early miners, the lead mining region became Wisconsin's most populous area at the time. The first capitol of the Wisconsin Territory was located for a short time at Belmont, Lafayette County in the heart of the lead mining region. The site of the first capitol is preserved at the First Capitol Historic Site. Three units of the Ice Age National Scientific Reserve are located within or adjacent to the Driftless Area: Devil's Lake State Park, Mill Bluff State Park, and Cross Plains State Park. In addition, the Ice Age Trail follows the Terminal moraine of the maximum glacial extent from the last ice age and enters the Driftless Area in several locations. Other notable natural features include the Baraboo Range (consisting of two heavily forested, steep, rocky quartzite ridges with mountain-type scenery), rock formations in Natural Bridge State Park (Wisconsin), the forested bluffs, floodplains, islands, and sandbars in the Lower Wisconsin River State Riverway, the confluence of the Wisconsin River with the Mississippi River at Wyalusing State Park, Trempealeau Mountain State Natural Area in the Mississippi River valley at Perrot State Park, and the gorge and rock formations surrounding the Wisconsin River at the Dells of the Wisconsin River. The Black River State Forest protects a large area of the North Woods, rocky bluffs, sandy plains, and river shoreline on the northeastern edge of the Driftless Area that provides habitat for several wolf packs and one of Wisconsin's reintroduced elk herds. Iowa An area in northeast Iowa that shares similar topographic characteristics to the Driftless Area in southeastern Wisconsin is the Paleozoic Plateau. For counties inland from the Mississippi, evidence is largely confined to the valleys of streams and rivers. It encompasses all of Allamakee, and part of Clayton, Fayette, Delaware, Winneshiek, Howard, Dubuque, and
