Which part of Wisconsin was not covered by the ice advance and what is this region called?
The Driftless Area escaped much of the scouring and depositional action by the continental glaciers that occurred during the last ice age, which created significant differences in the topography and drainage patterns within the unglaciated area compared to adjacent glaciated regions.
When was the last glacier in Wisconsin?
The Wisconsin glaciation extended from approximately 75,000 to 11,000 years ago, between the Sangamonian Stage and the current interglacial, the Holocene. The maximum ice extent occurred approximately 25,000–21,000 years ago during the last glacial maximum, also known as the Late Wisconsin in North America.
Where are the glaciers in Wisconsin?
The glacier valley where Glacier Valley Campground is located is an east-west valley created by the furthest reaches of the Green Bay lobe of the last glacier, part of the Laurentide Ice Sheet, some 20,000 years ago. The same glacier created lake Michigan.
Why is it called Wisconsin glaciation?
Wisconsin Glacial Stage, most recent major division of Pleistocene time and deposits in North America (from 2.6 million to 11,700 years ago). It was named for rock deposits studied in the state of Wisconsin.
What caused the driftless area in Wisconsin?
The region’s distinctive terrain is due to its having been bypassed by the last continental glacier. The term “driftless” indicates a lack of glacial drift, the deposits of silt, gravel, and rock that retreating glaciers leave behind.
Why do they call it the driftless?
How Did the Wisconsin Driftless Area Get Its Name? This area’s name is derived from the fact that it was surrounded by glaciers during the last glacial period, yet remained untouched by passing glaciers. This caused some curious, and beautiful, topography in these areas drawing visitors year-round.
What is the mystery of the Driftless Area?

Why does the Driftless Area exist?
Why did glaciers miss one small corner of the Midwest, even though they covered all of the area around it? The driftless area gets its name from the total lack of glacial drift material in the southwest corner of Wisconsin. The area is home to unique species found nowhere else and is home to many other mysteries.

Did glaciers flatten land?
Thousands of years ago (about 16,000), during the Great Ice Age, glaciers covered Indiana. Once the glaciers melted, the dirt, rocks, and sand (known as glacial till) that were picked up by the ice were all that was left behind. This till filled any hills or valleys that previously existed, leaving the land flat.
What is the Driftless Area of the Midwest?
