(Middlesex) and Flint Creek valleys, and which drained the Najjles lake 

 eastward into the Keuka valle3\ This channel is a fine example of the 

 excavations produced by the ice-dammed Avaters in their escape over 

 low places uncovered by the receding ice-foot. It is a nearly straight 

 rock cut, al)out one mile long and 100 feet deep, partly in Hamilton 

 shales. It heads about one and one-half miles northeast of Middlesex 

 village, near the east edge of a swamp col. A north and south road 

 crosses near the head of the channel. The bottom of the channel is 

 about 100 feet wide, flat, smooth, and swampy, with uniform gentle grade, 

 falling perhaps 30 feet in the total length. The channel now carries no 

 stream. The elevation of the col is not accurately determined, but is 

 probably over 1,150 feet. The lower end of the channel is one mile 

 northwest of Potter village, on the west side of Flint Creek valley. Here 

 the ancient stream which cut the channel piled the debris into a large 

 delta in the expanded waters of the Hammondsport glacial lake. This 

 delta is further described below (see next page). 



With the opening of this outlet and the down-cutting of the channel 

 the Naples waters were so lowered that the Honeo3'e waters became a 

 separate lake, tributary to Naples, and the delta west of Naples village 

 was formed with strong terraces correlating witli the Potter outlet. The 

 waters of the Middlesex valle3% which joins the Canandaigua valle}" 

 southward, always remained an eastern arm of the Canandaigua waters. 



This lower water body, with outlet at Potter to Keuka Yalle}^ waters, 

 ought, strictly, to have a sejiarate nanie. It was not really the Naples 

 lake which overflowed at a higher level to the Cohocton river direct!}- 

 into southern drainage. In order to preserve the association we will 

 call it the Naples-Middlesex lake. 



The Newberr}^ waters never existed in the Canandaigua valle\^ (see 

 page 43). 



The Warren waters have left evidences about the shores in the form 

 of delta terraces at elevations about 8S0 feet. A good beach of the War- 

 ren waters may be seen about one mile west of Reeds Corners, along the 

 west side of the Canandaigua road, opposite the house of Mrs Gates and 

 beneath the house of Mrs R. V. Henr3^ The elevation is about 880 

 feet. 



Flint Creek Valley 



The Flint Creek valley, lying between Canandaigua and Seneca val- 

 leys, impounds no lake at present, but its features and histor}^ are sim- 

 ilar to those of the Finger lakes valleys. The north end of the valle}^ is 

 at Gorham village, partially blocked by moraine drift. From here south- 

 ward to Potter, about 8 miles, the valley bottom is occupied by a cedar
