to near Atlanta. The elevation of the lake is 687 feet. Naples lies about 

 100 feet higher. The walls of the valley here rise directly 800 or 900 

 feet, and the surrounding tableland is more than 2,000 feet above tide. 



DRAINAGE. 



A number of streams pour into the valley near Naples. From the 

 northwest comes West Hollow creek. This is joined from the west, not 

 far from the village, by Springstead brook. From the southwest comes 

 Naples brook with several tributary brooks, the main one being the 

 Garlinghouse, from the west. From the south comes Olney brook; from 

 the southeast Tannery Glen brook. All these minor streams united make 

 Naples creek, which, near its mouth, three and a half miles north of the 

 village, is joined by West river, the latter heading near Rushville, between 

 Canandaigua and Seneca lakes, and flowing southwest. 



DIVIDE AND CHANNEL. 



These streams all occupy deep valleys cut out of the tableland, and 

 head near streams flowing into other drainage systems. The lowest of 

 them all is West river; but this, coming from the northeast, was under 

 the ice while the southern divides were uncovered. The next lowest 

 divide is the col to the west, between the Springstead brook and the inlet 

 of Honeoye lake, but the northern outlet by Honeoye lake was also in 

 the earlier life of the lake dammed by ice. The lowest southward outlet 

 was over the col between Naples brook and the Cohocton creek, near 

 Atlanta (formerly Bloods), on the Erie and the Delaware, Lackawanna 

 and Western railroads. This divide has an altitude of about 1,340 feet. 



The outlet channel of the Naples lake is a good example of an aban- 

 doned river-bed. It is something over a mile long, 20 to 25 rods wide, 

 with banks 15 to 20 feet high and a flood-plain of varying width. It 

 heads at the divide among hills of drift, and pursuing a nearly straight 

 course it opens into the Cohocton valley about one mile northwest of 

 Atlanta station. The highway leading northwest from Atlanta into the 

 Naples valley crosses the channel by the house of William Rowe, at 

 which point the direction of the channel changes from south to west of 

 south (see figure 1, plate 19). 



No stream of consequence has occupied this channel since it was 

 abandoned by the overflow of the glacial lake, and the pavement of 

 cobbles and bowlders in the bottom of the channel is still well shown 

 through the vegetal accumulation. 



DELTAS AND WA TEE LE VELS. 



Fine deltas have been produced by all the side streams entering the 

 valley and debouching into the deep lake. They are fairly well pre- 

 served a^nd the terraces are conspicuous (see figure 2, plate 19).
