Description
The Hogthief Creek Fault Zone is part of complex system of faults along the northwest side of the Rock Creek Graben. The narrow zone has vertical displacements as great as 1,600 feet (480 m) in places. Some segments are downthrown to the northwest, others to the southeast. The authors cited above reported that the zone may include reverse faults, but they provide no details. The fault zone is hidden by Ohio River alluvium on the northeast, but it may extend into Kentucky. Southwestward, the Hogthief Creek merges into a highly fractured region. Previous researchers have referred to the Hogthief Creek Fault or Fault System, but it is properly defined as a fault zone.
