Seidner Dune and Swale Nature Preserve

Seidner Dune and Swale, a dedicated Indiana state nature preserve, protects globally rare dune-and-swale topography and floodplain marsh along a beautifully restored section of the Grand Calumet River. Rescued from surrounding heavy industry and noisy highways, the black oak savanna, prairie, and wetlands communities here feature impressive wildflower displays in the spring, summer and fall. Egrets and herons frequent the river and the wetlands. Waterfowl can be seen on the river throughout the year. Hawks, bald eagles, and falcons hunt from high overhead, and aquatic mammals and turtles are increasing in number.
