Seidner Dune & Swale
This 43-acre property is a dedicated state nature preserve located in the City of Hammond. The site protects globally rare dune-and-swale topography and floodplain marsh along the Grand Calumet River. Natural communities here include black oak savanna, sand prairie, sedge meadows, cattail marsh, and buttonbush swamp. The black oak savanna and interdunal wetlands communities provide habitat for a diverse variety of flora and fauna. Impressive wildflower displays include wild lupine and puccoon in the spring and fringed gentians and prairie plants in the fall. Egrets, herons, and cormorants are often sighted along the river during the summer. An informal hiking trail exists along the frontage road and former railway rights of way.

The sandy savanna habitat at Seidner surrenders itself in spring to the blue and yellow of wild lupine and puccoon. Snapping turtles crawl out of the swales to nest on high, sandy areas. In summer come deep-orange Turk’s cap lilies and an abundance of prairie wildflowers. Delicate blue fringed gentians brighten the property in fall.
From I-94, exit at Kennedy Ave. north. Take Kennedy Ave. about 2.5 miles, just past the series of overpasses that carry U.S. 20, the South Shore Railroad, and Indiana Toll Rd. over Kennedy Ave.. Turn right(east) onto first road, which leads to the back end of the Resco plant. Park at bend in road and walk through the cable gate onto the dirt road leading east.
