The name "Grover" was applied by Rubey (1952) to the brown chert gravel and associated red sand that occur on upland surfaces in the type area and in Calhoun County, Illinois. In that region the gravel truncates Pennsylvanian and older bedrock formations and was deeply weathered and eroded before deposition of the Loveland Silt of Illinoian age.
The gravels are situated up to 70 m (230 ft) above regional floodplains. At the time of deposition, chert gravels occupied the lowest topographic positions--stream channels--in the surrounding landscape. Preservation of exotic-bearing gravels in drainage-divide positions demonstrates a wholesale inversion of topography in eastern Kansas.Chert gravel deposits in uplands of the Walnut basin have received little previous study.

Chert is a biochemical sedimentary rock made from microcrystalline quartz. It is very hard - registering a 7 on the Mohs hardness scale, and displays conchoidal fracturing. Chert can almost any color, but is usually gray, brown, red, or green. It has many subvarieties including flint, jasper, agate, and onyx.
Chert is a sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO 2 ). It occurs as nodules, concretionary masses, and as layered deposits. Chert breaks with a conchoidal fracture, often producing very sharp edges.
Annual precipitation (averaging 835 mm) and humidity are lower than within the Central Tallgrass Prairie to the east, and plant species richness is lower. The limestone bedrock dates to the Permian Period, with numerous bands of chert or flint.
