Adeline Jay Geo-Karis Illinois Beach State Park, part of the Illinois state park system, is located along Lake Michigan in northern Lake County in northeast Illinois. Together with lands to the north, including Chiwaukee Prairie, it forms the Chiwaukee Prairie Illinois Beach Lake Plain, an internationally recognized wet-land of importance under the Ramsar Convention. [2] The park is broken into two units that encompass an area of 4,160 acres (1,683 ha) and contains over six miles of Lake Michigan shoreline. In 2010, it was renamed for former state senator Adeline Geo-Karis.
Recreational activities at the park include boating, swimming, hiking, bicycling, camping, bird watching, and picnicking. [3] Known primarily for the beach, the park also includes dune areas, wetlands, prairie, and black oak savanna. The area at the far southern end of the park is a designated nature preserve, which was named a National Natural Landmark in 1980. [4]
The park was gradually created starting in 1948 when the state acquired the first parcels. The northern unit, acquired between 1971 and 1982, was previously an Illinois National Guard training facility known as Camp Logan, Illinois. During the American Civil War, Camp Logan was a Union prisoner of war camp.
In 1958, the Illinois Beach Hotel was opened within the park. [5]
The park is located in the 12 mile long Zion Beach Ridge Plain. The Zion Beach Ridge Plain is 3,700 years old and composed of curvilinear ridge-and-swale topography. The beach ridges support black oak savanna habitat, while wetlands dominate the swales. The Zion Beach Ridge Plain has been migrating south throughout the late Holocene: the northern portion of the beach ridge erodes; freed sediment is then transported through the dominantly southward littoral drift and deposited on the southern portion of the beach ridge. This erosion and subsequent accretion process created the characteristically curved ridges and swales of the park as the complex migrates south. [6] The northern unit of Illinois Beach State Park experiences rapid rates of erosion, which was exacerbated by the construction of North Point Marina in 1989 and reaches highs of 60 ft per year. The southward migration of the beach ridge plain has been disrupted by the construction of Waukegan Harbor. [7] Erosion in the north unit of the park is exacerbated during periods of high lake level. As Lake Michigan has entered a period near record high lake levels since 2014, the park is experiencing rapid transgression of the shoreline.
The entry to the beach is usually from a parking area on its north side: north of this carpark is usually the most crowded area in the summer time. South, the beach is less crowded and a mile of shoreline extends to an inlet into a wetland. Depending on weather conditions this inlet may be blocked by a berm from the lake waters, and again depending on weather conditions the water inside the berm may be significantly warmer than Lake Michigan which is rather cold until August. [8]
Prairies are ecosystems considered part of the temperate grasslands, savannas, and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and a composition of grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type. Temperate grassland regions include the Pampas of Argentina, Brazil and Uruguay, and the steppe of Ukraine, Russia, and Kazakhstan. Lands typically referred to as "prairie" tend to be in North America. The term encompasses the area referred to as the Interior Lowlands of Canada, the United States, and Mexico, which includes all of the Great Plains as well as the wetter, hillier land to the east.

Indiana Dunes National Park is a United States national park located in northwestern Indiana managed by the National Park Service. It was authorized by Congress in 1966 as the Indiana Dunes National Lakeshore and was redesignated as the nation's 61st national park on February 15, 2019. The park runs for about 20 miles (32 km) along the southern shore of Lake Michigan and covers 15,349 acres (6,212 ha). Along the lakefront, the eastern area is roughly the lake shore south to U.S. 12 or U.S. 20 between Michigan City, Indiana, on the east and the Cleveland-Cliffs steel plant on the west. This area's conservation scheme is enhanced by the older Indiana Dunes State Park. To the west of the steel plant lies West Beach and a small extension south of the steel mill continues west along Salt Creek to Indiana 249. The western area is roughly the shoreline south to U.S. 12 between the Burns Ditch west to Broadway in downtown Gary, Indiana. In addition, there are several outlying areas, including Pinhook Bog, in LaPorte County to the east; the Heron Rookery in Porter County, the center of the park; and the Hoosier Prairie State Nature Preserve and the Hobart Prairie Grove, both in Lake County, the western end of the park.
The Kankakee River is a tributary of the Illinois River, approximately 133 miles (214 km) long, in the Central Corn Belt Plains of northwestern Indiana and northeastern Illinois in the United States. At one time, the river drained one of the largest wetlands in North America and furnished a significant portage between the Great Lakes and the Mississippi River. Significantly altered from its original channel, it flows through a primarily rural farming region of reclaimed cropland, south of Lake Michigan.
A swale is a shady spot, or a sunken or marshy place. In US usage in particular, it is a shallow channel with gently sloping sides. Such a swale may be either natural or human-made. Artificial swales are often infiltration basins, designed to manage water runoff, filter pollutants, and increase rainwater infiltration. Bioswales are swales that involve the inclusion of plants or vegetation in their construction, specifically.
Northwest Indiana, nicknamed The Region after the Calumet Region, is an unofficial region of northern Indiana, United States that is located at the northwestern corner of the state. Though there is no official definition of the region, it is based on the Gary, Indiana Metropolitan Division, which comprises Jasper, Lake, Porter and Newton counties in Indiana, and the Michigan City-La Porte, IN Metropolitan Statistic Area, which comprises LaPorte, with unofficial definitions also including Starke and Pulaski counties. This region neighbors Lake Michigan and parts of it are in the Chicago metropolitan area. According to the 2020 Census, the largest definition of Northwest Indiana has a population of 866,965 and is the state's second largest urban area after the Indianapolis Metropolitan Area. It is also the home of the Indiana Dunes, parts of which have been preserved through conservation efforts. The town of Ogden Dunes houses the Hour Glass, a museum showcasing the ecological and conservation efforts of O. D. Frank.
Lake Chicago was a prehistoric proglacial lake that is the ancestor of what is now known as Lake Michigan, one of North America's five Great Lakes. Formed about 13,000 years ago and fed by retreating glaciers, it drained south through the Chicago Outlet River.
A beach ridge is a wave-swept or wave-deposited ridge running parallel to a shoreline. It is commonly composed of sand as well as sediment worked from underlying beach material. The movement of sediment by wave action is called littoral transport. Movement of material parallel to the shoreline is called longshore transport. Movement perpendicular to the shore is called on-offshore transport. A beach ridge may be capped by, or associated with, sand dunes. The height of a beach ridge is affected by wave size and energy.
Powderhorn Lake, within Illinois but close to the state line, is a 48 acres (19 ha) lake that is part of the sand wetlands of the Indiana Dunes, most of which are located in the nearby state of Indiana. It is the centerpiece of the 192 acres (78 ha) Powderhorn Lake Forest Preserve, part of the Forest Preserve District of Cook County in Cook County, Illinois.

Camp Logan, Illinois was an Illinois National Guard base and rifle range from 1892 to the early 1970s. At one time the Camp was 200 acres (0.81 km2). Several buildings survive today as they are listed on the National Register of Historic Places.
The Indiana Dunes comprise ten different habitats. Each provides for a unique combination of plants and animals. The range of the Indiana Dunes varies depending your source. The Indiana Lake Michigan Coastal Program uses the river drainage systems along the shoreline. This expands the area from the areas of lakeshore southward to the edges of the Valparaiso Moraine. This entire region has been dune landscapes since over 114,000 years before present (YBP). Traditionally, the Indiana Dunes area thought of as a narrow area along the shores of Lake Michigan, including the areas of Marquette Park in Gary, Indiana (1920), Indiana Dunes State Park (1926) and Indiana Dunes National Park,. The identified ten habitats can be found in these parks, where they have been preserved, but are also visible throughout the three counties of Northwest Indiana.
The Kankakee Torrent was a catastrophic flood that occurred about 19,000 calibrated years ago in the Midwestern United States. It resulted from a breach of moraines forming a large glacial lake fed by the melting of the Late Wisconsin Laurentide Ice Sheet. The point of origin of the flood was Lake Chicago. The landscape south of Chicago still shows the effects of the torrent, particularly at Kankakee River State Park and on the Illinois River at Starved Rock State Park.
At a flat coast or flat shoreline, the land descends gradually into the sea. Flat coasts can be formed either as a result of the sea advancing into gently sloping terrain or through the abrasion of loose rock. They may be basically divided into two parallel strips: the shoreface and the beach.
