What Makes This Part of Iowa Different Than The Rest?
Nestled in the northeastern corner of Iowa lies the Driftless Area, a region unlike any other in the state. Covering approximately 8% of Iowa, this area includes Allamakee, Clayton, Winneshiek, and Fayette counties, as well as parts of nearby counties. Its striking landscape sharply contrasts with the flat or gently rolling terrain typical of the rest of Iowa, offering a rugged, unglaciated terrain that tells a story millions of years in the making.

What is the Driftless Area of Iowa?
The Driftless Area owes its distinctiveness to a fascinating quirk of geological history: it was untouched by the glaciers that covered much of the Midwest during the last Ice Age. While glacial activity flattened and smoothed much of the region, the Driftless Area remained free from the scouring and sediment deposits that shaped neighboring landscapes. The result is a rugged topography featuring steep bluffs, deep ravines, narrow valleys, and winding ridges. Limestone cliffs and outcroppings further add to the dramatic scenery, especially along the Mississippi River, which forms the eastern border of the region.
One of the defining characteristics of the Driftless Area is its karst topography. This unique geological feature is the result of water eroding the limestone bedrock over millennia, creating caves, sinkholes, and underground streams. Visitors to the region can explore some of these features at places like Decorah Ice Cave State Preserve or Maquoketa Caves State Park, just outside the boundaries of the Driftless Area.
The biodiversity of the Driftless Area is another standout feature. Its varied habitats—from forests and prairies to wetlands and cold-water streams—support a wide array of plant and animal life. The region is home to many species not commonly found elsewhere in Iowa, including brook trout, which thrive in the region’s pristine, spring-fed streams. Birdwatchers are drawn to the area as well, particularly to spots like Effigy Mounds National Monument, which offers both ecological richness and historical significance as a sacred site for Native Americans.
Beyond its natural beauty, the Driftless Area is a hub for outdoor recreation. Hiking, fishing, and canoeing are popular activities, and scenic drives, such as the Great River Road, showcase the area’s breathtaking vistas. Towns like Decorah add to the charm, offering a mix of cultural attractions, including the Vesterheim Norwegian-American Museum and local breweries.
The Driftless Area extends significantly into both Wisconsin and Minnesota as well. Most of the Driftless Area lies in southwestern Wisconsin, covering over 16,000 square miles. This is where the region's unique features are most pronounced, with rolling hills, deeply carved river valleys, and extensive karst landscapes. In southeastern Minnesota, the Driftless Area spans roughly 10,000 square miles. The region includes counties such as Fillmore, Houston, and Winona, where visitors can explore the Root River Valley, the bluffs along the Mississippi River, and other scenic spots like Whitewater State Park.
The Driftless Area is a hidden gem within Iowa, offering visitors a chance to experience a landscape and heritage unlike anywhere else in the Midwest. Whether you’re drawn to its geological wonders, rich biodiversity, or outdoor adventures, this unique region is well worth exploring.
