Before the surrounding area was settled, Cheyenne Bottoms was an intermittent marshland in a 64-square-mile basin. In the 1950s, the state of Kansas began developing it into a more permanent and stable wetlands and wildlife area. Dikes now divide the marsh into a series of pools, and water is diverted between pools to maintain suitable habitat. Like their relatives—starfishes, sea urchins, sea cucumbers, and brittle stars—crinoids are echinoderms, animals with rough, spiny surfaces and a special kind of radial symmetry based on five or multiples of five. Crinoids have lived in the world's oceans since at least the beginning of the Ordovician Period, roughly 485 million years ago.

Concretion. Concretions are masses of mineral matter embedded within rock layers, including limestone, sandstone, and shale. They often take shape when minerals precipitating (settling) out of water collect around a nucleus, such as a pebble, leaf, shell, bone, or fossil. Concretions most often form in sediment before or as the sediment is ...The Kansas High Plains region is an area of vast flatlands and gently rolling plains. Topographic relief is largely restricted to streams and river valleys and is most notable in the Arikaree Breaks in the far northeast corner of the state, at Point of Rocks along the Cimarron River in the far southwest corner, and around Lake Scott State Park.Kansas DRG Maps. View the entire list of USGS Kansas Digital Raster Graphic Maps.Concretions in Kansas are formed from any of a number of minerals, including calcite, limonite, barite, pyrite, or silica. They vary widely in shape and size, with the huge spherical concretions at Rock City in Ottawa County and Mushroom Rock State Park in Ellsworth County measuring up to 27 feet in diameter. A special type of concretion, known ...Shale is the main component of the Wellington Formation, which underlies the Arkansas River Lowlands east of Hutchinson. Up to 700 feet thick, the Wellington is composed of mostly shale, with interspersed layers of salt, limestone, siltstone, and anhydrite. It was deposited early in the Permian Period, about 275 million years ago.The High Plains Aquifer Atlas, compiled by the Kansas Geological Survey, features more than 70 maps—several animated or interactive—that can be used to investigate such timely topics as changes in groundwater levels and availability of groundwater over time, water use, water rights, and the region's climate conditions. Four animated maps in ...Gypsum. A common mineral in Kansas, gypsum is calcium sulfate with two molecules of water (CaSO 4 •2H 2 O). Calcium sulfate without water is the mineral anhydrite (CaSO 4 ). It is colorless or white to light gray (or, rarely, bright red) and is so soft that it can be scratched by a fingernail. Gypsum is divided into three varieties.The KGS county geologic mapping program makes basic geologic information about the state available to the public.

Recent Earthquakes from the Survey's Network.The 1:24,000-scale (7.5 minute) series maps are the most detailed topographic maps available for Kansas. Each map covers an area of approximately 6.5 by 8.5 miles and shows towns, lakes, rivers, creeks, ponds, roads, railroads, quarries, pipelines, radio towers, airports and landing strips, townships, vegetation, cemeteries, and rural buildings.Water in Kansas. In most years, precipitation in the form of rain, sleet, or snow is greatest in eastern Kansas and gradually declines toward the west. The wettest spot, on average, gets 45 inches per year and the driest less than 20 inches. As a result, eastern Kansas has more surface water — rivers, creeks, lakes, and wetlands.Clams and their relatives (oysters, scallops, and mussels) are often called bivalves (or bivalved mollusks) because their shell is composed of two parts called valves. Bivalves have a long history. Their fossils first appear in rocks that date to the middle of the Cambrian Period, about 510 million years ago.Explore Northeast Kansas.

Sphalerite is an ore—a mineral of economic value—that was once mined in southeastern Kansas for its zinc content. It is also called zinc blende, blende, blackjack, and mock lead. Sphalerite crystals are usually shaped like triangular pyramids, with three sides and a base. Because it has good cleavage in six directions, sphalerite will break ...The U.S. Public Land Survey System (PLSS) was established shortly after the Revolutionary War as a way to describe and record parcels of land for legal purposes.The Flint Hills were formed by the erosion of Permian-age limestones and shales. During the early part of the Permian Period (about 299 to 252 million years ago), shallow seas covered much of the state, as they did earlier in the Pennsylvanian subperiod. Unlike the Pennsylvanian limestones found at the surface to the east, many of the ... Data Resources Library at the Kansas Geological Survey.
