Indiana Dunes National Park dominates the Lake Michigan shoreline, preserving a complex environment of sand and marshland that contrasts with the urban grid of Michigan City. This survey illustrates the intricate drainage network of the Calumet region, where Carver Ditch, Kintzele Ditch, and Brown Ditch channel water through low-lying areas south of the shoreline dunes. The shoreline itself is anchored by the prominent Mt Baldy, situated between the residential developments of Long Beach and the protected parklands.
