Geology Of Mammoth Cave National Park, Kentucky, Matthew M. Crawford, Rickard A. Olson, Rickard S. Toomey Iii, Lillian J. Scoggins

Map and Chart--KGS

Mammoth Cave National Park in south-central Kentucky was authorized as a national park in 1926 and was fully established in 1941 to protect the cave system, scenic landscape, and diverse flora and fauna. The park contains 52,830 acres and most of the longest recorded cave system in the world, with more than 390 miles of mapped passages as of 2013. Even though Mammoth Cave is famous, people are often unaware of the park's intricate connection to the outside region. This poster shows the geology of Mammoth Cave and the interconnected issues that are important to the park and its visitors. …

Kentucky Terrain, Daniel I. Carey, Terry D. Hounshell

Map and Chart--KGS

The terrain of Kentucky has been shaped by geologic forces and the underlying rocks.Tectonic forces lifted, bent, and buckled the rocks–originally formed from sediments on shallow sea floors or swampy lowlands. Weathering and erosion shaved the hills and dissected the plains, exposing at the surface a cross section of rocks 250 to 500 million years old. The sands, gravels, silts, and clays of the Jackson Purchase Region are younger, remnants of a time when the sea lapped at the confluence of the Mississippi and Ohio Rivers.

The landforms in Kentucky are the result of the differential weathering of interbedded sandstones, …

Geologic data were derived from the Kentucky Geological Survey-U.S. Geological Survey areal geologic mapping project. Nearly 190 geologists mapped the geology of Kentucky from 1960 to 1978. KGS geologists converted the resulting 707 geologic quadrangle maps into digital format at part of the STATEMAP component of the National Cooperative Geologic Mapping Program of the United States Geological Survey.
