Name Origin

The Pounds Sandstone Member of the Caseyville Formation (Weller, 1940, p. 38), the uppermost member, is named for Pounds Hollow in Gallatin County.

Type Section

The type section consists of exposures along Pounds Hollow (35, 36, 10S-8E).


The Pounds is correlated with part of the Mansfield Sandstone of Indiana and the upper Caseyville conglomerate, or Bee Springs Sandstone Member, of western Kentucky.

Extent and Thickness

The Pounds Sandstone reaches 100 feet thick, forming long, abrupt bluffs in southern Illinois, usually north of the Battery Rock bluff. The Pounds is also known as far north as Rock Castle Creek in Randolph County (33, 6S-5W).


The Pounds Sandstone is lithologically similar to the Battery Rock Sandstone. Like other members of the Caseyville Formation, the Pounds Sandstone has not been widely traced in the subsurface north of the outcrop belt, although strata of this age and lithologic character are known to be present (fig. P-9).
