The Onion River and the North Branch Milwaukee River define the glacial hydrology of this Sheboygan County landscape. This 2022 survey details the complex terrain formed during the last ice age, featuring the prominent Parnell Esker and the Greenbush Kettle, both vital landmarks for understanding the regional geomorphology. The Ice Age National Scenic Trail winds through these landforms, connecting the small settlement of Parnell with the surrounding ridges and depressions.
