Pg. 438. Boggy shale. Alternating shales and sandstones, nearly 3,000 feet thick, overlying Savanna sandstone and underlying Thurman sandstone. Contains not less than 16 beds of sandstone, 20 to 150 feet thick, separated by shale beds 100 to 600 feet thick. Age is Pennsylvanian (Allegheny). Report includes geologic maps.
Named from exposures along North Boggy Creek, Pittsburg and Atoka Cos., OK.
[GNC remark (ca. 1938, US geologic names lexicon, USGS Bull. 896, p. 226): The base of Boggy shale in McAlester district is now drawn by the USGS at base of or 20+/- feet below Lower Witteville coal.]

Pg. 504, 510-511. Boggy shale. Only lower part of formation exposed in Muskogee County, Oklahoma. Includes (ascending) shale, Crekola sandstone member (new), shale, Inola limestone member, shale, Taft sandstone member (new); Secor or Upper Witteville coal occur in shale beds below the Crekola. Fossils. Thickness 172+ to 242+ feet. Conformably overlies Savanna sandstone. Rocks formerly included in Winslow formation. Age is Pennsylvanian. Report includes geologic map, columnar sections, measured sections.
[Misprint: US geologic names lexicon (USGS Bull. 1200, p. 411) lists Inola sandstone member. Should be Inola limestone member.]

[Pennsylvanian System by C.C. Branson, p. 63-68.] Pg. 68. Boggy formation of Krebs group. As defined by the Oklahoma Geol. Survey, comprises strata from base of Bluejacket sandstone member to unconformity at base of Cabaniss group. Age is Middle Pennsylvanian (Des Moines).

Pg. J333-335, pl. 16. Boggy formation of Krebs group. In Oklahoma, exposed in wide arcuate belt from southeastern Pontotoc County and central and northern Coal County through Pittsburg, Haskell, and McIntosh Counties to northwestern Muskogee County. From there it has been mapped northward to Kansas line. Large outliers remain in Sansbois syncline in Haskell and Latimer Counties, where more than 2,000 feet of formation is present, and in Cavanal syncline to LeFIore County, where as much as 3,000 feet of rocks to formation make up much of Cavanal Mountains. Complete continuous section in Pittsburg County is about 2,850 feet thick. Overlies Savanna formation; underlies Thurman sandstone. Includes Secor and Lower Witteville coal beds. Age is Middle Pennsylvanian (Des Moines).
