Jack Masters and Joe Devera care- fully critiqued the geological map. Heinz Damberger, as project leader of COGEOMAP, provided continuous encouragement and advice. Private land- owners in the study area are gratefully acknowledged for permitting access to outcrops on their land. In particular, we thank Sam Michaels, Herman Stokes, and Leonard Jones, who allowed us to drill stratigraphic tests on their land.

Geography and Physiography The Lick Creek Quadrangle is in JACKSON southernmost Illinois between lati- tudes 37'30' and 37'37'30" N and SALINE GALLATIN WILLIAMSON longitudes 89O00' and 89O07'30" W (fig. 1). Highway access to the area is ------- provided by Interstate highway K 57 (1-57) between Marion and Cairo. The Lick Creek and Goreville inter- changes are within the quadrangle. Paved and graveled county roads provide access to most of the study area, except for areas around the Crab Orchard National Wildlife Refuge, where access is by foot trails. Two unincorporated villages, Lick Creek and Wayside, are in the quad- 20 mi rangle, but the latter is a "ghost" 30 km town. Approximately three-fourths of the quadrangle is privately owned, and most of the remainder is in the Shawnee National Forest. The quadrangle is within
