Mauylaxd Geological SltyVey -JG9 



pon, West Virginia. This is the locality from which the Woodmont 

 member is named. Tlie strata, which stand nearly vertical, are exposed 

 in the cnts of tlio Western Maryland Eailroad, where there is an uninter- 

 rnpted section of tlie lower 1400 feet, rivalling the section at Berkeley 

 Springs, West Virginia, in its excellence. The section is somewliat 

 thinner than usual, due probably to the compression of the strata in the 

 west limb of the anticline, a feature frequently seen in Appalachian folds. 

 It begins at the Eomney-Jennings contact west of Tonoloway Statiim, 

 and extends westward along the railroad 1291 feet, from which point it is 

 continued on the hillside north of the railroad.
