Description

The Clinton Syncline is a broad, shallow trough that plunges south and has a sinuous axis. Maps of the Danville Coal Member (Pennsylvanian; Clegg 1972) and the top of the Galena Group (Champlainian; Bristol and Buschbach 1973) show no internal closure. The west flank is gentle, and the east flank merges with the west flank of the Downs Anticline which is part of the La Salle Anticlinorium.
