Pg. 10. Pine sandstone member of Pottsville formation. Quartzose, coarse, and thick-bedded sandstone at base, but finer-grained and more flaggy at top. Thickness 250 feet. Is a member in lower part of Pottsville formation in Cahaba and Coosa coal fields. Immediately or closely overlies Roper coal. Age is Pennsylvanian.
[Named from Pine Ridge in Birmingham quadrangle (scale 1:125,000), Jefferson (and St. Clair) Cos., central AL.]

Pg. 22, fig. 2. Pine sandstone member of Pottsville formation. Shown on columnar section (St. Clair County, central Alabama) as light-gray to light-brown friable conglomeratic sandstone 210 to 250 feet thick; in lower part of formation, stratigraphically above Shades sandstone member and separated from it by 200 to 230 feet of claystone, siltstone, and sandstone; underlies about 2,800 feet of sandstone, siltstone, and carbonaceous claystone with thin coaly beds. [Age is Early Pennsylvanian (Pottsville).]

Pg. 70. Pine Sandstone Member of Pottsville Formation. A thick-bedded, coarse-grained, quartzose conglomeratic sandstone, which grades upward to a flaggy fine-grained sandstone. Occurs in lower part of Pottsville Formation in Coosa and Cahaba coal fields, southern Valley and Ridge province, lying 200 to 1,000 feet above the basal Shades Sandstone Member. Increases in thickness from 250 feet in the northern part of the Cahaba coal field to 400 feet in the southern part. Thickness in the Coosa coal field ranges from 200 to 500 feet. [Age is Early Pennsylvanian (Morrowan).]
