Corresponding layers in the floor and the roof are strikingly 

 prominent. Unquestionably the swelling of the anhydrite 

 caused faulting, and entrance from the surface is by way of 

 the fault space. The throw is about four feet and the horizontal 

 displacement about three feet. It is possible that a deeper 

 chamber was the seat of activity, but if so it lies below 

 lake level and the_ presence of water prevented exploration. 

 No occurrence of slickensides was noted, due perhaps to the 

 fact that the partial doming accompanying the faulting elimi- 

 nated shear. 



2. Duff's Cave. This lies just above ground-water level. 

 Note correspondence in floor and roof, and degree of displacement. 



Fundamentally Victory Cave is similar, differing only in 

 proportions. The descent averages 40°, and is broken at but 

 one point, where for a distance of fifteen feet it is vertical. 

 From entrance to ground water level is about 150 feet, on slope. 

 Masses of loose rock obscure true conditions. Certainly it is 

 not a cave in the usual meaning of the term. Here again is 

 evidence of faulting, with a throw of five feet and little or no 

 horizontal displacement. No chamber was found — the open 

 fault continues without a break to lake level, where the water
