The database contains a set of measured sections (precise measurements and descriptions of a cross section of an outcrop or roadcut) for selected counties in Kansas. The data is based on archived materials from the Kansas Geological Survey, with sections created from 1900's to 1950's. The graphic columns have been scanned or scanned and traced from the original copies, and the descriptions have been typed in. Current stratigraphic nomenclature may be different than that presented on these pages, and some of these outcrops may no longer exist or may not be accessible.
