Pg. 656, 657, 763. Churn Creek member of Cuyahoga formation. Argillaceous shale with an occasional thin sandstone passing gradually into underlying Vanceburg sandstone member. Thickness 50 to 100 or more feet. Present only in southwestern part of Scioto and eastern Adams Counties, southern Ohio, and only in vicinity of Buena Vista is Logan formation found overlying it. Is top member of Cuyahoga formation in southwestern Scioto County. [Cuyahoga as used above includes lower part of Black Hand formation, to which these beds belong. Age is Mississippian.]
Named from Churn Creek, southeastern part of Adams Co., southern OH.

Pg. 77, 134, pl. 6. Churn Creek shale member of New Providence formation. In upper part of New Providence column in Lewis County, Kentucky, siltstone beds become fewer as well as thinner, with argillaceous to silty shale becoming prevalent; no sharp break occurs between these two divisions. This upper zone, 75 to 100 feet thick, is interpreted as the "Churn Creek" of Hyde (1915) and termed Churn Creek shale member. Occurs above Vanceburg siltstone member in Vanceburg facies of formation. Age is considered Early Mississippian.

Pg. 173; Jour. Geol., v. 50, no. 1, p. 41 (table 2), 63-64. Churn Creek siltstone and shale member included in Vanceburg facies of Logan formation in Ohio. Underlies Vinton sandstone member; overlies Vanceburg siltstone member, but no dependable horizon separates the two, distinction being made on the basis of larger sandstone content of Vanceburg. [Age is Early Mississippian.]

Pg. 3 (table 1), 25. Churn Creek member of Cuyahoga formation. Here considered member of Cuyahoga formation in Vanceburg facies. [Age is Early Mississippian.]
Editor's note states Hyde (1921, Ohio Geol. Survey Bull., no. 23) correlated Buena Vista sandstone with Berne and lower portion of Byer in discussing geology of Camp Sherman quadrangle; such a correlation would necessitate placing Rarden, Vanceburg, Churn Creek, and most of Portsmouth shale in Logan formation.

Pg. 145, 147, 219 (Chart 19), 226, 229, 283. Churn Creek member of New Providence formation. Age is considered Early Mississippian (Osagean) based on forams REOPHAX MCDONALDI n. sp. and HYPERAMMINA sp. fragments. R. MCDONALDI occurs only in Churn Creek member in Kentucky and in Black Hand sandstone member of Cuyahoga formation of Ohio.
R. MCDONALDI type specimen collected from roadcut along Vanceburg-Tannery Road, beginning 1.25 mi south of Chesapeake and Ohio RR station at Vanceburg, Lat. 38 deg. 35 min. 05 sec. N., Long. 83 deg. 19 min. W., Vanceburg quadrangle, Lewis County, Kentucky (measured section of Stockdale, 1939, p. 98, 99).
