The Late Cretaceus Niobrara Formation in south central Nebraska
Excellent outcrops of Niobrara and Pleistocene strata can be seen near Franklin and Bloomington (Exposures 1 and 2, Fig. 1; Figs. 2-5) in Franklin County. The Niobrara Formation generally dips westward at about 15 ft/mi (3 m/km), and at the western end of the outcrop area in Harlan County, the Niobrara is conformably overlain by the Pierre Shale.
All of the outcrops are road cuts and are within public access. The outcrop near Franklin has a very steepnorth slope and a fairly gentle east slope. The section at the Bloomington bridge is very steep but negotiable by persons without physical limitations. The outcrops near Red Cloud are fairly steep but are also negotiable by persons without physical limitations.
