Pg. 712. Florena shales below (2 to 13 feet thick) and Neosho member above (130 feet thick), with aggregate thickness of 140 to 145 feet, are now united to form Garrison formation, so named on account of good exposures from Garrison south in Big Blue Valley. Included in Council Grove stage. Occurs above Cottonwood limestone and below Wreford limestone.
Named from exposures at Garrison, Pottawatomie Co., eastern KS.
[GNC remark (ca. 1936, US geologic names lexicon, USGS Bull. 896, p. 803): This name was continued in use for many years.]

Garrison formation of Council Grove group. Includes (descending): Speiser shale restricted, Funston limestone, Blue Rapids shale, Crouse limestone, Easly Creek shale restricted, Middleburg limestone, Hooser shale, Eiss limestone, Stearns shale, Morrill limestone, and Florena shale members. Overlies Cottonwood limestone of Council Grove group; underlies Wreford [limestone] of Chase group. Recognized in southeastern Nebraska and eastern Kansas. Age is Permian (Big Blue).

Pg. 50 (fig. 12). †Garrison shale of Council Grove group. In diagram showing comparison of old and revised classification of beds referred to lower part of Big Blue series of "Permian" age, Garrison shale is replaced with (ascending) Beattie limestone (includes Florena and Morrill limestone members), Stearns shale, Bader limestone (includes Eiss limestone, Hooser shale, and Middleburg limestone members), Easly Creek shale, Bigelow limestone (includes Crouse limestone, Blue Rapids shale, and Funston limestone members), and Speiser shale.

Garrison shale of Council Grove group. In 1936 (Kansas Geol. Survey Bull., no. 22, p. 50, 251) R.C. Moore discarded the name, treating the numerous named subdivisions into which it had in recent years been differentiated as formations within Council Grove group. The USGS has not yet had occasion to reconsider retaining the name for its publications [ca. 1938].

Pg. 103-105. Garrison shale of Council Grove group. As used in this report, Garrison shale is top unit of Council Grove group. Includes beds upward from top of Cottonwood limestone to base of Wreford limestone. Name was discarded by Moore (1936) who raised various members of Garrison shale to formation rank. Formations constituting Garrison section in Kansas cannot be identified in Pawnee County, northern Oklahoma, and general term Garrison shale has been retained. Interval consists of poorly exposed heterogeneous sequence of red shales and red to tan lenticular sandstones. Thickness difficult to determine. About 140 feet in subsurface, slightly west of outcrop. Age is Permian.

Pg. 6 (fig. 3), 7. Garrison Shale of Oscar Group. In Noble County, central northern Oklahoma, only uppermost part exposed in inliers in eastern part of T. 24 N., R. 3 E., beneath Wreford Limestone, and upper 30 feet exposed in T. 21 N., R. 3 E. Mostly red claystone. Age is Late Pennsylvanian (Gearyan); oldest formation exposed in county.
