Description

This fault zone has been known by several names, including the Albion Fault, Ridgway Fault, Ridgway-Omaha Monocline or Fault Zone, and Albion-Ridgway Fault. The name is revised to Albion-Ridgway Fault Zone to reflect the compound nature of faulting in the area. The fault zone consists of a series of high-angle, normal faults that mark the western edge of the Wabash Valley Fault System. The southern part of the zone strikes due north; northward, it curves to the north-northeast. Individual faults are straight to gently arcuate along the strike and overlap slightly end-to-end. Displacements are down to the east to as much as 430 feet (130 m).
