Eastside was a large infertile sandy area that was never homesteaded or developed. It was designated Marquette National Forest byPresident Theodore Roosevelt in 1909. This land was administered with Huron National Forest as the Michigan National Forest from 1918 intil 1962, when it was transferred to Hiawatha. The forest was authorized to buy an additional 307,000 acres (124,200 ha) in 1925 and 50,000 acres (20,230 ha) in 1935. Westside began being purchased in 1928 and was designated Hiawatha National Forest in 1931. This unit was extensively replanted by the Civilian Conservation Corps.
The forest has over 100 miles (160 km) of shoreline. Both east and west units have shoreline on both Lake Superior and Lake Michigan; the east unit also has shoreline onLake Huron and includes Round Island and its lighthouse. The west unit borders Pictured Rocks National Lakeshore, which is administered by the National Park Service, and the Grand Island National Recreation Area, which is separately administered by the U.S. Forest Service.
Several lighthouses are located along the shores. The Point Iroquois Light is operated as a museum. The segment of the 4,600-mile-long North Country Trail passes through the forest.
