Greene–Sullivan State Forest was established in 1936, originating from a significant land donation. Coal companies, including Indiana Central Coal Company, generously contributed over 3,000 acres of their former mining properties to the Indiana Department of Natural Resources, Division of Forestry. Over the subsequent decades, the forest expanded considerably through additional donations and acquisitions from other companies like Maumee and Sentry Royal Coal Company. This growth increased its total acreage to nearly 9,000 acres, transforming reclaimed strip-mined lands into the diverse woodland and lake-filled landscape seen today.
