Glaciers are large masses of ice that travel slowly and move like a river. In the most recent glacial period, nearly all of Wisconsin was covered in ice. This was called the Wisconsin Ice Age. This ice age started 75,000 years ago and lasted 12,000 years. Some of these pieces of ice were 5,000 to 10,000 feet thick.
Although this area was unglaciated (not covered by glaciers), the glaciers still left many effects, like the bluffs. The glacier’s great amount of pressure pushed up the bluffs, and formed many hills and valleys. Swiss Valley’s large hills were caused by the amount of pressure from the glaciers.
Mining and settlement of the area would have been different.
