The 11-acre Skunk Lake is a deep, hard water marl lake with very clear water fed by seepages and springs. A wetland dominated by cat-tails and bulrush surrounds the lake and a navigable channel connects it to Foster Lake, a 7-acre shallow, hard water, muck-bottom lake. The lake is ringed with cat-tails and arrowhead with numerous submerged aquatics. Surrounding the lakes is second-growth northern dry-mesic forest with sugar maple, red oak, big-tooth aspen, paper birch, and white oak. The topography is uneven with numerous glacial erratics strewn about. Grenlie Lake is a small, clear, hard water lake fed by seepage and springs and a small inlet from an adjacent marsh.
