The boundary follows the 45-mile shoreline and the approximately 52 miles along an east-west trajectory across the Valparaiso Moraine. The western extent of the inland boundary lies along the Indiana-Illinois state line. The northern extent lies along the lakeward boundary and the Indiana-Michigan state line in LaPorte County.
