Dune And Swale
Ridge and swale, or in dunal areas dune and swale, is a landform consisting of regular, parallel ridges alternating with marshy depressions. Ridge-and-swale landscapes are most commonly formed by the gradual movement of a beach, for example as a result of gradually fluctuating water levels, or the shifting meanders of a river. In the river context, ridge-and-swale landscapes are commonly formed by scroll bars. They are also found along ocean coasts, for example on the Outer Banks of North Carolina. Great Lakes ridge and swale Freshwater ridge-and-swale ecosystems are globally rare and found only in parts of the Great Lakes of North America. They were formed as a result of the gradual retreat of beaches due to falling water levels and post-glacial rebound. The swales and the adjoining lake or river commonly form a single hydrological unit, so that rising or falling lake levels will cause water levels in the swales to rise or fall as well. Most ridge-and-swale landscapes have been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dune
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''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in other areas where poorly cemented sa ...

Michigan Wilderness State Park
Wilderness State Park is a public recreation area bordering Lake Michigan, five miles southwest of Mackinaw City in Emmet County in Northern Michigan. The state park's include of shoreline, diverse forested dune and swale complexes, wetlands, camping areas, and many miles of hiking trails. The state park is operated by the Michigan Department of Natural Resources, which has, as of 2006, approved a proposal that be officially dedicated as a wilderness area. Wilderness State Park was designated a Michigan "dark sky preserve" in 2012. Description One of the most prominent physical features of the park is Waugoshance Point, which juts westward into northern Lake Michigan. Beyond the tip of the point, Temperance Island and Waugoshance Island are also parts of the state park. Four Lake Michigan lighthouses sit near the park's western boundary. Stations at Grays Reef, Skillagalee Island, Waugoshance, and White Shoal warn shipping away from the dangerous reefs and shoals ...

Shirley Heinze Land Trust
The Shirley Heinze Land Trust, originally known as the Shirley Heinze Environmental Fund, is a 501(c)(3) nonprofit land trust dedicated to the preservation of natural areas in Northwest Indiana. The Heinze Trust manages more than 2,800 acres of protected land in Lake, Porter, LaPorte, St. Joseph, Starke, and Marshall Counties in Indiana. Its preserves include a wide range of dune, wetland, prairie, and forest ecosystems. Due to the heavily developed nature of the Calumet Region, many of the Heinze Trust's parcels are entirely surrounded by industrial or residential development. Many of the preserves were severely degraded when first acquired, and the Heinze Trust has engaged in a wide range of restoration activities in order to restore them to ecological viability. The Heinze Trust's preserves include six designated Indiana Nature Preserves, some of which were purchased with funds from the Indiana Heritage Trust. History and Mission The Shirley Heinze Environmental Fund was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Miller Woods
Miller Woods is the far western unit of Indiana Dunes National Park in the lakefront community of Miller Beach, Indiana. Miller Woods is home to the federally endangered Karner Blue butterfly and the federally threatened Pitcher's thistle. Miller Woods is also the only part of the National Park that also adjoins the Grand Calumet River. The northern part of Miller Woods adjoins Lake Michigan, and includes foredunes and high dunes, as well as blowouts and pannes. The southern and larger part of Miller Woods consists of rolling ridge and swale, with beach ridges dominated by oak savanna. This southern part is also traversed by current and former rail lines. The northern and southern parts are divided by the Grand Calumet River, including the westernmost of the three lagoons that mark the river's modern-day headwaters and former mouth.

Nature Preserves
A nature reserve (also known as a wildlife refuge, wildlife sanctuary, biosphere reserve or bioreserve, natural or nature preserve, or nature conservation area) is a protected area of importance for flora, fauna, or features of geological or other special interest, which is reserved and managed for purposes of conservation and to provide special opportunities for study or research. They may be designated by government institutions in some countries, or by private landowners, such as charities and research institutions. Nature reserves fall into different IUCN categories depending on the level of protection afforded by local laws. Normally it is more strictly protected than a nature park. Various jurisdictions may use other terminology, such as ecological protection area or private protected area in legislation and in official titles of the reserves. History Cultural practices that roughly equate to the establishment and maintenance of reserved areas for animals date back to ...

Landform
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features.

Calumet Region
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 bypr ...
