Pg. 64-65. Condra (1935) employed term Bigelow limestone as comprising (ascending) Sabetha limestone (Crouse limestone), Blue Rapids shale, and Funston limestone. The Bigelow thus included strata between the Easly Creek shale and Speiser shale. To be consistent with classification applied to strata above and below them, these beds should be divided into formations. Proposed that Bigelow be dropped as stratigraphic term and that Crouse limestone, Blue Rapids shale, and Funston limestone be recognized as formations. Gives origin of name.
Named from Bigelow, Marshall Co., northeastern KS.
