Garden of the Gods Recreation Area, Shawnee National Forest, Saline County, Illinois. Sandstone is of fluvial origin. Cut-and-fill structures, extensive cross-bedding, and steeply dipping joints are conspicuous. (Pounds Sandstone Member, Caseyville Formation) Back: Circular, suboval, and irregular Liesegang banding. These iron-oxide- rich bands are believed to be the result of repeated uniform precipi- tation from colloidal suspension in porous and permeable sandstone. About one-third actual size.

Due to long-term deep water deposition (Heckel, 1977) have been pro- and continuing studies of surface exposures and a large posed to explain the origin of these shales. The black amount of widely distributed subsurface data, the char- shale will be accessible for close exmination at several acter of strata of the Pennsylvanian System throughout outcrops, and various sedimentary features will be most of the area of the Illinois Basin is probably as well identified. known as any comparable area in the world. This field excursion will be devoted to examining Demonstration of broad lateral continuity of some natural and man-made exposures which provide infor- coals and other rock units in the Illinois Basin.
