The Dr. J.S. Garman Nature Preserve is a wooded hillside within the City of Waterloo. Steep topography on the west side of the park levels out at the top of the hill where 22 Indian Mounds are found. The woods include oak, hickory, maple and cherry species. Some pines and spruce were planted at one time within the woods and along the north edge. The entrance to the park is located on Fox Lane off of McKay Way and Knowlton Street.
