The Calumet Region is the geographic area drained by the Grand Calumet River and the Little Calumet River of northeastern Illinois and northwestern Indiana in the United States. It is part of the Great Lakes Basin, which eventually reaches the Atlantic Ocean. It is a sub-region of the greater Northwest Indiana region and the even larger Great Lakes region. This region includes the northern parts of Lake and Porter counties and the western portion of La Porte county in Indiana, as well as the eastern counties of northern Illinois, Will and Cook.Since much of this region is on the south shore of Lake Michigan, it is sometimes referred to as the "South Shore". Because it was initially cut off from the rest of the state due to natural geographic barriers like the Kankakee Marsh to the south, the Calumet Region was the last-settled portion of Indiana.The area is known for its industrial heritage and history as a center for production of steel, minerals and chemicals. The toxic byproducts of these industries present major issues for public safety and natural resource management today. The region was a center for the labor rights movement of the 1930s. The Memorial Day massacre of 1937, where ten steelworkers' rights activists were killed by police officers during a demonstration, occurred on Chicago's southeast side.Today, Calumet is notable as a site of many habitat restoration projects. The area contains many endangered dune, Swale, and moraine based ecosystems. Many Forest Preserve District of Cook County sites, such as Powderhorn Prairie, 95th/Dan Ryan Woods, and Eggers Grove are being restored under the care of volunteer stewards. In addition, nonprofit groups partner with the Forest Preserve District and Chicago Park District to complete larger-scale restoration projects. Major partners include The Field Museum, the Wetlands Initiative, and local branches of The Nature Conservancy, Green Corps and the Student Conservation Association. Many of these sites have become host to locally rare and threatened species like Blanding's turtle, Wilson's phalarope and the least weasel.
