272 H. L. FAIRCHILD — LAKE WAEEEN SHOEELINES: GENEVA BEACH. 



trine episode. In either case it adds an interesting fact to the history of 

 the glacial waters in their fall from the Warren level to the final Iroquois 

 stage, and at the present writing a puzzling fact, since the correlating 

 outlet channel has not been found. 



The special purpose of this writing is to place the following facts of 

 observation on record in sufficient detail for others to find and observe 

 the phenomena. 



Maps. 



The maps accompanying this paper, and which form figures 1, 2, and 

 3 of plate 30, are intended to indicate, by the heavy solid lines, the loca- 

 tion of the beaches with reference to highways, streams, etcetera. It has 

 not been practicable to show the character of the beach, whether cliff or 

 bar or spit, but this is generally stated in the verbal descriptions in the 

 text. In most cases the beach-lines represent well defined ridges or em- 

 bankments. 



Warren Shoreline. 



from crittenden to indian falls. 



One mile southwest of Crittenden the Lehigh Valley railroad crosses 

 the beach obliquely by a cutting. This affords an accurate determina- 

 tion of the altitude of the beach, w r hieh at this point is 858 feet above 

 mean ocean level. 



The village of Crittenden lies upon the broad, low ridge of fine gravel 

 and sand to which the name of the village was given many years ago by 

 Mr Gilbert (see plate 30, figure 1).* 



For over a mile going northeast the ridge is traversed by the highway, 

 which then, turning more to the east, leaves the beach a short distance 

 upon the northward for nearly two miles. West of the north-and-south 

 county line road the beach has been wholly removed for a space by an 

 extensive excavation by the New York Central railroad. East of the 

 county line the beach is divided into two or more embankments, and is 

 less definite for a fraction of a mile, but recovers its usual strength before 

 reaching the next north-and-south road. The houses of Miss Hair and Mr 

 John Brown are located upon the beach at the road intersection. One- 

 third of a mile farther east the ridge suddenly terminates on the border 

 of Murder Creek valley. Nearer the creek some knolls of sand occur, 

 which may be fragments of the eroded beach. Beyond the creek or 

 northward the ridge reappears, but is irregular, and soon disappears in 

 a kame-moraine surface. Perhaps even here more thorough search will 

 identify the beach-line. A wave-cut cliff may be seen further east. 



The beach reappears about one mile north, near the intersection of two
