Pg. 17 and table C. Swope limestone member of Bethany Falls limestone. Revised correlation by R.C. Moore, 1931 [unpublished?], divides Bethany Falls limestone in vicinity of Kansas City into (descending) Swope limestone, Sugar Creek shale, and Middle Creek limestone. Age is Late Pennsylvanian (Missouri age).

Pg. 100. Base of Swope formation is variable, since the lower limestone members are less persistent than Bethany Falls limestone, the upper member. In all cases Swope formation includes strata from top of Bethany Falls limestone as defined in reports of Missouri Geol. Survey down to base of lowest lens of limestone, which is a few feet below the Bethany Falls and which is persistent over several miles. This excludes blue flaggy beds which are present a few feet below Swope formation in southern Linn and northern Bourbon Counties, eastern Kansas. Age is Late Pennsylvanian (Missouri age).

Pg. 90, 97. Swope limestone of Bronson group. The beds from top of Bethany Falls limestone down to base of Schubert Creek limestone (which overlies Ladore shale [restricted], clearly represent a single sedimentation cycle and are here named Swope formation. They are divided into (descending): Bethany Falls limestone [restriction of R.C. Moore's 1931 definition and replaces Swope limestone of his 1931 list of names], Hushpuckney shale [= Sugar Creek shale], Middle Creek limestone, Elm Branch shale, Sniabar limestone, Mound City shale, Critizer [Critzer] limestone, Tennison Creek shale, and Schubert Creek limestone (called "Hertha" by Hinds and Greene). Age is Late Pennsylvanian (Missouri age).

Pg. 26-29. Swope limestone of Bronson group. Swope limestone is proposed by Moore and Newell for the persistent limestones and thin shales from top of Ladore shale [restricted] to top of Bethany Falls limestone. In Johnson and Miami Counties, northeastern Kansas, divided into (ascending) Middle Creek limestone, Hushpuckney shale, and Bethany Falls limestone. Age is Late Pennsylvanian (Missouri age). [On p. 26 he also stated that Ladore shale of southern Kansas may include representatives of Middle Creek limestone and Hushpuckney shale. Named from Swope Park, Kansas City, Missouri.]

Pg. 37. Swope limestone of Bronson group. Definition of Swope formation is modified to exclude beds below Middle Creek limestone, because nowhere else in Missouri series has a well-defined "lower" limestone (in terms of Shawnee cycle) been found. [On p. 78 Moore stated Swope limestone of his 1932 definition (Kansas Geol. Soc. 6th Ann. Field Conf. Gdbk.) includes beds classed in his 1936 paper as Hertha limestone, Ladore shale, and Bethany Falls limestone.] Age is Late Pennsylvanian (Missouri age).

Pg. 2028-2029, 2031 (fig. 4). Swope limestone included in Kansas City group (redefined in Kansas and Nebraska). Comprises (ascending) Middle Creek limestone, Hushpuckney shale, and Bethany Falls limestone members. Overlies Ladore formation; underlies Galesburg formation. Bronson reduced to [informal] subgroup of Kansas City group (redefined). This is classification agreed upon by Geological Surveys of Iowa, Kansas, Missouri, Nebraska, and Oklahoma, May 1947. Age is Late Pennsylvanian (Missourian).
