Join Barbara Petersen’s bird walk for a late fall exploration of Clark Lake Park.The park offers a variety of habitat types and bird species. Follow trails to the lake and through forest, wetland, meadow and even an old orchard. We’ll walk one to two miles at a leisurely pace searching for waterfowl, raptors and returning migrants. Bring binoculars, spotting scopes, cameras, warm layers, water and snacks.
