Stratigraphic relationships
The Wayside is the lowermost unit of the Pennsylvanian System on the western side of the southern Illinois outcrop belt.
Extent and thickness
Lithology
Like the Lusk, the Wayside is a complex unit of interbedded lenticular sandstones as much as 50 feet thick that are separated by silty or sandy shales and siltstones, all part of a fluvial-deltaic complex. In the area south of Carbondale the thickness of the Wayside varies but averages about 70 feet.
