GLACIAL WATERS IN THE LAKE ERIE BASIN

road. The lowest, with altitude 847 feet, lies under the highway 

 north of the overhead crossing of the Lehigh Valley Railroad and 

 its north end swings around east as a recurved hook. The higher 

 bar lies $ mile east, and is occupied north of the Lehigh Railroad 

 by the Crittenden highway. Its altitude at the Lehigh crossing 

 is 857 feet. From this point north for about 2 miles the beach is 

 a single heavy bar, supporting the village of Crittenden. North 

 of the village the map gives the beach altitude as 860 feet. 



A mile northeast of Crittenden the beach splits into a diverging 

 or fan-shaped series of bars with nearly equal altitude, lying on 

 the delta built in Lake Warren by the latest glacial drainage from 

 the east, along the track of the present Murder creek. The south- 

 ernmost bar lies along the north side of an east and west road; 

 the most northern bar pursues a northeast course and supports a 

 road for a mile, approaching Pembroke. The lakeward side of the 

 shore in this stretch of 8 miles is a steep slope facing low, 

 swampy ground. 



The village of Pembroke lies on a shore or delta deposit of Murder 

 creek. Northeast from Pembroke for \\ miles the shore features 

 are too weak to map, but a good bar occurs a mile northeast of 

 Pembroke station under a north and south road, with its south end 

 curving east. Northeast of this bar and at four-corners south of 

 Indian Falls a bar is found supporting a cemetery, with elevation 

 of 869 feet. 



Up to Pembroke the Warren shore has been found in the form of 

 heavy bars, with direct course, and for long stretches has developed 

 to maturity. From Pembroke and Indian Falls eastward through 

 central New York the bars are usually faint and the shore line is 

 weak and very immature. The Warren shore west of Crittenden 

 must have felt the wave work several times longer than the shore- 

 line to the east of Indian Falls. The conclusion is that the glacier 

 front rested for a long time on the high ground north and west of 

 Batavia, and the Warren waters were then dammed off from 

 the land to the east. Other glacial waters were, however, doing 

 their work in that region. When the ice finally gave way and 

 permitted the Warren waters to enter central New York, it was but 

 a relatively short time before they were drained down by eastward 

 escape and the Lake Warren extinguished. 



From Indian Falls east to near Leroy the Warren shore lies along 

 the brow of the scarp of Onondaga limestone which forms 

 the high ground from northwest to northeast of Batavia. 

 The scarp was probably the result of long eras of preglacial
