CRAYFISHES FROM ALABAMA CAVES — RHOADES 145 



"Saddler Springs Cave is a typical underground stream that has 

 no connection with the surface. Apparently there has never been 

 the slightest bit of sediment or trash in the cave. Stalactites are 

 like crystal, and the floor of the stream is neatly carved out of 

 limestone rock with scarcely any sand or gravel anywhere in the 

 place. The crayfish fauna is somewhat limited, as are the other 

 faunas. 



"McFarlen Cave is some 700 feet long and of varying width. The 

 entrance is archlike and of easy access. The stream is located in 

 back of the cave, and is spring-fed. It is my impression that there 

 is no permanent water in the front portion of the cave. The water 

 level may have been higher in former times. Boulders are to be 

 found on the floor of the cave. No fish have been taken there. 



"Saltpeter Cave, in the Clear Creek area of Jackson County, is 

 located under a high bluff near the foot of a mountain. It is of the 

 fissure type. It is 1,895 feet long and most of its length is in the 

 zone of total darkness. The floor of the cave has a stream, evidently 

 permanent, and fed by several springs."
