Fairview cave is developed in a thrust sheet of the Chambersburg Limestone, very close to a contact with the Martinsburg Shale. The passages are found along a series of major north-south oriented joints in beds which dip 10º east and strike due north.
      A number of openings are developed near Fair-view in a low cliff forty feet above the west bank of Conococheague Creek. One is a large shelter-like entrance ten feet high and five feet wide, from which flows a spring. This cave extends along a joint trending south for almost forty feet, where it becomes too small to traverse. Several vertical chimneys and higher passage indicate a possible upper level to the cave.
      Two hundred feet southwest of this cave is an entrance which leads to a cave resembling Davies' description of Fairview Cave for the first thirty feet. Some question, however, exists as to whether this is the one he describes. Almost 400 feet of passage have been mapped in this very tight and muddy cave.
