a time the ice front held the river flow to a more direct westward 

 course by cutting across the brow of the hill south of Bennington. 

 EA^entually the waters were ponded in the broader section of the 

 Cayuga valley and an extensive delta was built above and below 

 Cowlesville. 



The subsequent and lower escape of the Tonawanda waters 

 (Attica lake) over to the valley of Cayuga creek, and later 

 directly into Lake Warren, has left striking records of river flow 

 over a large area. This area is partly in the northern edge of 

 Wyoming county but chiefly in the southern part of Genesee 

 county [see pi. 6]. The Erie railroad follows one of the channels 

 in the midst of the series, and the Delaware, Lackawanna & Western 

 Railroad lies in a lower one at Ray station. The latest flow was 

 along the lines of the Lehigh Valley and the New York Central 

 Railroads. The entire area is covered by the Alden-Batavia 

 moraine. 



All the north and south roads between Alden and Darien show 

 numerous waterways. The County line road, ij miles east of 

 Alden, shows several channels. These unite into two channels 

 and debouch at Warren level near the village where they helped 

 to form the extensive gravel plain, crowned with strong Warren 

 bars. On the road passing through Darien Center 14 channels 

 are found worthy of representation on the map; and an equal 

 number lie on the next road to the east. The higher of these 

 channels are 1200 feet. 



The lower ice border drainage in this region poured into Lake 

 Warren near Fargo station. The lowest lies along the south side 

 of the Lackawanna Railroad east of Fargo station, with altitude 

 about 900 feet. This channel terminates as a cut bank or bluff J 

 mile south of the station, facing the delta, the broad smooth g avel 

 plain that is bounded on the north by the railroad and on the west 

 by the County line road. Two strong gravel bars built by Warren 

 waves on the west margin of this delta lie across the north and 

 south Countyline road, i^ miles southwest of Fargo station, the 

 north one supporting the cemetery. These channels lying along 

 the Lackawanna Railroad have their heads north of Alexander and 

 pass through or south of Ray station. One and one half miles 

 west of Ray station and on the north side of the river channel is 

 a broad gravel plain that was deposited as an outwash from the 

 glacier, while the course of the glacial river which fed it is marked 

 in the strong esker or sinuous gravel ridge which partly supports 

 the crooked north and south road. The level of this plain, about
