Description

This feature is part of an intensely fractured zone southeast of the apex of Hicks Dome. The Illinois Furnace Fault trends northeast and intersects other faults at both ends. Maximum displacement is more than 500 feet (150 m), with the southeast side downthrown. J. Weller et al. (1952) stated that "thrust faulting is probably locally important," but provided no details.
