Ice covered Wisconsin and Sheboygan County numerous times after the onset of the Ice Age approximately 2.7 million years ago. However, only evidence of the most recent advances remain. This report traces the advances and retreats of the glaciers. Sheboygan County contains three main physiographic regions, each representing a record of unique ice deposits and erosion.

The Kettle Moraine region formed about 20,000 years ago between two thinning ice lobes and is interpreted to have been a large braided river system on top of stagnant ice. On either side of the Kettle Moraine lie regions of outwash and till. These features are distinguished by drumlins, pitted outwash plains, large meltwater channels, and lake plains. The eastern edge of the county is defined by low-relief end moraines and gently rolling, clayey plains.
