The village is located in the Southeastern Wisconsin glacial till plains that were created by the Wisconsin glaciation during the most recent ice age. Much of the community is located on the Saukville Reef formation, which is part of the Racine Dolomite that stretches through eastern Wisconsin and Illinois. The formation contains Silurian marine fossils, and while much of the rock lies between 25 and 50 feet below the surface, it's exposed at some old quarries in the northern part of the village.
