Description

This fault is part of the complicated, extensively mineralized system of fractures near Rosiclare on the southeast side of the Rock Creek Graben. The Hillside Fault strikes north and has the west side downthrown as much as 200 feet (60 m). The Hillside fluorspar vein reportedly reached a width of 34 feet (10.3 m), the greatest of any vein in the Illinois-Kentucky Fluorspar District.
