Description
The Elmwood Syncline, northernmost of the Peoria Folds, trends slightly north of east and is about 26 miles (42 km) long. Structural relief is 40 to 50 feet (12-15 m) and the fold is roughly symmetrical as mapped on the base of the Pennsylvanian. The fold becomes asymmetrical on deeper horizons and has a steeper north limb.
