Summary:

Pg. 44, 47. Spring Branch limestone bed of Lecompton limestone member of Shawnee formation. Basal unit of Lecompton limestone, is exposed in northwestern Missouri and northeastern Kansas; probably not exposed in Nebraska. Massive above and chalky and friable below. Weathers yellowish or brownish. Thickness in Missouri and Kansas 4 to 8 feet. Underlies Doniphan shale and overlies Kanwaka shale member. Age is Late Pennsylvanian (Missouri age). Report includes cross sections, measured sections, geologic maps, stratigraphic tables.
Named from exposures on Spring Branch north of Big Springs, [Douglas Co.], northeastern KS.

Summary:

Pg. 163, footnote. Spring Branch limestone, basal member of Lecompton limestone of Shawnee group. The absence of Spring Branch and "Curzen" limestones in Nebraska has been recognized by Condra. Conclusion that Spring Branch limestone is absent in Nebraska may require modification when restudy of correlation of "Plattsmouth limestone" section of Snyderville quarries and other places in Nebraska has been completed, for it is possible topmost part of "Plattsmouth" as previously identified may prove to be Spring Branch limestone. Age is Late Pennsylvanian (Virgil).
