The Greenbush trails dish out some tough kettle moraine riding. Kettle moraine is the geographical equivalent of Swiss Cheese. The last great glacier formed deep hollows with steep sides that were made when huge, building-sized ice blocks were churned in with glacial till. After the glacier retreated and the ice blocks melted, deep pits formed. These make a rocky, roller coaster bike ride. Kettle, or interlobate moraine, can be found where two glacial ice sheets ground against each other. In the Kettle Moraine State Forest they got a real workout.
On Kettle Moraine Drive, 2.5 miles north of State Highway 67.
