Summary:

Pg. 94, 96. Heumader shale member of Oread limestone of Shawnee group. Thin shale near top of Oread limestone, underlying Kereford limestone member and overlying Plattsmouth limestone member. Age is Late Pennsylvanian (Virgil). [On p. 52 it is described as consisting of 2 feet of dark-bluish shale with thin yellow streaks.]

Wilmarth, Secretary of Committee on Geologic Names, USGS unpub. corr. chart, Oct. 1936, sheet 2


Summary:

Pg. 48, 167-168. Heumader shale member of Oread limestone of Shawnee group. The few feet of shale that lies between base of Kereford limestone, where that member is present, and top of Plattsmouth limestone may be termed Heumader shale and classed as a member of Oread formation. The shale is clayey to sandy and usually appears dark gray. Thickness almost 0 to 10 feet. Where Kereford limestone is absent the Heumader and possibly shaly equivalents of the Kereford are not differentiated. Although stratigraphic continuity with units classified as parts of Oread formation is recognized, the shale next above the Plattsmouth is then included with Kanwaka shale. Age is Late Pennsylvanian (Virgil).
Type locality: Heumader quarry, bluffs of Missouri River just north of St. Joseph, Buchanan Co., northwestern MO.
