The shape of the failure surfaces can be inferred from the mappable features at the ground surface. The head of the landslide consists of a narrow zone, as much as 4-5 m wide, of extensional faults and cracks. The faults and cracks are vertical to steeply dipping downslope. The horizontal offset of Delhi Pike is smaller than the vertical separation of blocks of displaced road (fig. 4). Bulges and other indications of shortening are evident at the first break in slope downslope from the head. These bulges apparently reflect predominantly horizontal displacement; a cistern that was originally about 3 m from the stone wall (Mr. Dale Schmale, oral commun., 1980) near boring 14 is now only 2 m away, and the wall has not been perceptibly displaced vertically.
