Introduction. 



Through the work of the Rogers brothers in Pennsylvania and Virginia 

 and of SafFord in Tennessee, the characteristic forms of Appalachian structure 

 have long been familiar to geologists. The unsymmetrical fold has been 

 recognized as the normal structural form through Pennsylvania, Maryland, 

 and a portion of Virginia. In east Tennessee, the reversed fault, transverse
