Gibson Woods Nature Preserve

Tucked away in the heart of the industrial region of northwest Indiana is an island of nature with some very unusual features. This 131-acre parcel of virtually "undisturbed" land is known as Gibson Woods Nature Preserve . . . a Lake County Park. The dune and swale features of the preserve were produced after the last glacier created ancient Lake Chicago, the forerunner of Lake Michigan. The parallel sand ridges still found in Gibson Woods today represent the effect of Lake Chicago as it retreated thousands of years ago.
