A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes with little or no vegetation are called ergs or sand seas. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter slip face in the lee side. The valley or trough between dunes is called a dune slack.
A swamp is a forested wetland. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates periodic inundation or soil saturation. The two main types of swamp are "true" or swamp forests and "transitional" or shrub swamps. In the boreal regions of Canada, the word swamp is colloquially used for what is more correctly termed a bog, fen, or muskeg. Some of the world's largest swamps are found along major rivers such as the Amazon, the Mississippi, and the Congo.
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; it covers 15,349 acres (6,212 ha) of various acreage. 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 ArcelorMittal steel plant on the west. 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 Calumet Prairie State Nature Preserve and the Hobart Prairie Grove, both in Lake County, the western end of the park.
Carolina bays are elliptical to circular depressions concentrated along the Atlantic seaboard within coastal Delaware, Maryland, New York, New Jersey, North Carolina, South Carolina, Virginia, Georgia, and north Florida. In Maryland, they are called Maryland basins. Within the Delmarva Peninsula, they and other coastal ponds are also called Delmarva bays.
Southwick Beach State Park is a New York State park that lies along an unusual stretch of sandy beach on the eastern shore of Lake Ontario. The park is 464 acres (188 ha) in size with a 3,500 foot (1,100 m) length of beach, and is visited annually by about 100,000 people. Immediately to the south is the Lakeview Wildlife Management Area, which extends the publicly accessible beach by several miles. They are in the Town of Ellisburg in Jefferson County, New York south of the lakeside community of Jefferson Park.
Jones Lake State Park is a North Carolina state park in Bladen County, North Carolina in the United States near Elizabethtown. It covers 2,208-acre (8.94 km2), including the Carolina bay lakes of Jones Lake and Salters Lake. Jones Lake State Park is north of Elizabethtown on North Carolina Highway 242 in North Carolina's Coastal Plain region. The park offers year-round recreation, including fishing, swimming, boating, hiking, picnicking and environmental and historical education programs.
Lake Waccamaw State Park is a North Carolina state park in Columbus County, North Carolina, in the United States. Located near the town of Lake Waccamaw, North Carolina, it covers 2,398-acre (9.70 km2), along the shores of Lake Waccamaw, a Carolina bay. Recent work by the U.S. Geological Survey has interpreted the Carolina Bays as relict thermokarst lakes that formed several thousands of years ago when the climate was colder, drier, and windier. Thermokarst lakes develop by thawing of frozen ground (permafrost) and by subsequent modification by wind and water. Thus, this interpretation suggests that permafrost once extended as far south as the Carolina Bays during the last ice age and (or) previous ice ages.
Pettigrew State Park is a North Carolina State Park in Tyrrell and Washington Counties, North Carolina in the United States. It covers 5,951 acres (24.08 km2) around the shore lines of Lake Phelps and the Scuppernong River. The park's developed facilities are south of U.S. Route 64 near Roper and Creswell, North Carolina. Pettigrew State Park is open for year-round recreation, including hiking, camping, fishing, boating and picnicking.
Singletary Lake State Park is a North Carolina state park in Bladen County, North Carolina in the United States. Located near Elizabethtown, it covers 1,221-acre (4.94 km2), including Singletary Lake, one of the largest Carolina bays. Singletary Lake State Park is southeast of Elizabethtown on North Carolina Highway 53 in North Carolina's Coastal Plain region. It serves primarily as a group camp but is open on a limited basis for year-round recreation, including hiking, fishing and observing nature.
Lake Waccamaw is a fresh water lake located in Columbus County in North Carolina. It is the largest of the natural Carolina Bay lakes. Although bay trees are present within many Carolina Bays, the term "bay" does not refer to the trees but comes instead from an early science publication by Glenn (1895), who used the word "bay" to refer to these features near the town of Darlington, South Carolina. Lake Waccamaw is fed by four creeks: First, Second, Third, and Big creeks. The outlet forms the Waccamaw River which flows southeasterly to empty into the Atlantic Ocean near Georgetown, South Carolina
The Sandhills or Carolina Sandhills is a 10-35 mi wide physiographic region within the U.S. Atlantic Coastal Plain province, along the updip (inland) margin of this province in the States of North Carolina, South Carolina, and Georgia. The extent of the Carolina Sandhills is shown clearly in maps of the ecoregions of North Carolina, South Carolina, and Georgia.
Thermokarst is a terrain-type, characterised by very irregular surfaces of marshy hollows and small hummocks formed as ice-rich permafrost thaws. The land surface type occurs in Arctic areas, and on a smaller scale in mountainous areas such as the Himalayas and the Swiss Alps.
Sandy Island Beach State Park is a New York State park on the eastern shore of Lake Ontario. Its highlight is a 1,500-foot (460 m) natural sandy beach. The park is near the southern end of a notable 17-mile (27 km) length of sandy shoreline, coastal dunes, and wetlands ; a 1959 study noted that "The eastern end of Lake Ontario contains not only the finest beaches on the entire lake but also the finest wildlife habitat."
Cowles Bog is a 4,000-year-old wetland complex in Indiana Dunes National Park, near Chesterton, Indiana. It is named for Henry Chandler Cowles who did his pioneering work in ecology and ecological succession here. His work brought international attention to the area which led to efforts to preserve the Indiana Dunes. It was designated a National Natural Landmark in 1965. It contains bog, fen, marsh, wet meadow, swamp, and pond habitats.
Raised bogs, also called ombrotrophic bogs, are acidic, wet habitats that are poor in mineral salts and are home to flora and fauna that can cope with such extreme conditions. Raised bogs, unlike fens, are exclusively fed by precipitation (ombrotrophy) and from mineral salts introduced from the air. They thus represent a special type of bog, hydrologically, ecologically and in terms of their development history, in which the growth of peat mosses over centuries or millennia plays a decisive role. They also differ in character from blanket bogs which are much thinner and occur in wetter, cloudier climatic zones.
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.
Woods Bay State Park is a state park located near the town of Olanta in Florence County, South Carolina. The park contains some of the last remaining large Carolina Bays. Recent work by the U.S. Geological Survey has interpreted the Carolina Bays as relict thermokarst lakes that formed several thousands of years ago when the climate was colder, drier, and windier. Thermokarst lakes develop by thawing of frozen ground (permafrost) and by subsequent modification by wind and water. Thus, this interpretation suggests that permafrost once extended as far south as the Carolina Bays during the last ice age and (or) previous ice ages.
Little Pee Dee State Park is a state park located near the town of Dillon in Dillon County, South Carolina. The park land includes a part of a Carolina Bay and adjacent sand rim. Recent work by the U.S. Geological Survey has interpreted the Carolina Bays as relict thermokarst lakes that formed several thousands of years ago when the climate was colder, drier, and windier. Thermokarst lakes develop by thawing of frozen ground (permafrost) and by subsequent modification by wind and water. Thus, this interpretation suggests that permafrost once extended as far south as the Carolina Bays during the last ice age and (or) previous ice ages.
Lewis Ocean Bay Heritage Preserve is a 10,427-acre natural preserve near Carolina Forest, South Carolina. It is named for one of many Carolina Bays. Recent work by the U.S. Geological Survey has interpreted the Carolina Bays as relict thermokarst lakes that formed several thousands of years ago when the climate was colder, drier, and windier. Thermokarst lakes develop by thawing of frozen ground (permafrost) and by subsequent modification by wind and water. Thus, this interpretation suggests that permafrost once extended as far south as the Carolina Bays during the last ice age and (or) previous ice ages.
