Loess is a finely ground silt that is deposited by the wind. In the High Plains of Kansas, loess was deposited by the wind during the Ice Ages of the past million years. This finely ground silt was formed as glaciers advanced over the continent, pulverizing rocks and sediments in their path. When the glaciers melted, this silt was deposited on ...Covering much of Clark, Barber, and Comanche counties, the Red Hills, sometimes called the Gyp Hills, also spill over into adjacent counties in Kansas and Oklahoma. Although gypsum in the Red Hills is more resistant to weathering than the other rocks and sediments, it is an evaporite left behind as the seas dried up and, thus, soluble in water.Fossils in Kansas. Fossils specimens: Delocrinus, Acanthoceras, Meganeuropsis. Many Kansas rocks are full of fossils, the remains of plants or animals that have been preserved in rock. Through fossil finds, geologists and paleontologists piece together evidence of earlier life and landscapes on Earth.Salt is mined in Kansas using two methods: underground mining and solution mining. Underground mines in Kansas range in depth from 500 to 1,000 feet. With the underground room-and-pillar method of mining, a shaft is drilled through overlying rock to reach the salt deposit. The salt is removed in a checkerboard pattern so that large square ...

In Kansas, surface water is more abundant in the eastern part of the state, where higher annual precipitation replenishes rivers, lakes, and wetlands on a fairly regular basis. Groundwater is more plentiful in western Kansas, where the expansive High Plains aquifer provides almost all of the water used in the region. In between, surface water ...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.
