A prominent topographic lineament lays adjacent and parallel to the southeastern margin of the Reelfoot Rift. Recent paleoseismological studies suggest the southern segment of the lineament corresponds to a pair of steeply dipping strike-slip faults. However, the northern segment of the lineament is seismically quiescent and was mapped as a fluvial terrace riser by several geologists in the past. To ascertain whether the northern segment of the lineament could have been produced by faulting, the concavity of the lineament's slope was quantified and compared to that of several known fault scarp and terrace riser slopes. A hypsometric analysis was performed in order to assess whether any surface deformation related to faulting might have occured along the lineament, and electrical resistivity tomography was used to image subsurface features. When combined, results from these analyses strongly suggest mid-Quaternary faulting is responsible for creating the northern segment of the rift margin lineament.
