FEATURES OF THE NAPLES LAKE. 3G3 



1. Tlie highest level, the Garlinghouse, is the height of the lake outlet. 

 The lowering of the outlet by the stream-cutting and the erosion of the 

 plateaus has given an indefinite surface to these terraces, which are not 

 yet measured, but they are surely above the col. This level shows at 

 the top of all the deltas as the broad plateau. It makes the plain at 

 the head of the Garlinghouse delta, three miles southwest of the village, 

 the plain above the Tannery Glen delta southeast, and shows as erosion 

 terraces and benches in various parts of the valley. 



2. The Crippen level is the top of the delta made by the Springstead 

 brook and West Hollow creek, immediately over the village on the west. 

 Corresponding levels are found on the Tannery Glen delta. The alti- 

 tude is 1,192 feet. 



3. The main Springstead level is 1,127 feet. This is the broader ex- 

 panse of the Springstead delta, a pronounced plateau above the village. 

 It was produced by tlie overflow of the ice-dammed waters of Honeoye 

 lake. 



4. Oak Hill level, 1,114 feet, is a lower terrace of the Springstead delta. 



5. Brauns Hill level, 1,088 feet, is another still lower terrace of the 

 Springstead delta. A corresponding terrace is Tylers orchard, south of 

 the village one and one-half miles. 



6. Cemetery level is a well developed terrace of the Springstead-West 

 Hollow creeks delta, but consists of two or three minor benches. Two 

 altitudes taken were 1,011 and 1,002 feet. 



7. Bobnick level, 909 feet, is named after the local appellation of the 

 lowest of the terraces. Corresponding levels are seen on the east side of 

 the valley at Hinkley's vineyard, on Hatch hill, and also at the top of 

 Parrish Gully delta, two miles northeast of the village. 



LAKE HISTORY. 



The history of this lake is complicated, and is involved with that of 

 the glacial Honeoye lake. At its maximum the glacial lake was more 

 than 600 feet above the present lake, Avhich has a depth of over 200 feet. 

 Its waters were then united with those of the ice-dammed Honeoye and 

 reached far up the branching valleys. The outlet was over the southwest 

 col to the Cohocton creek. At this stage were built the up])er terraces 

 of the Garlinghouse delta, of the Tannery Glen delta, and of the West 

 Hollow creek delta and other plateaus. From this level the lake did not 

 fall suddenly, l)ut by a series of depressions, as the ice-removal uncovered 

 the land between this lake and the glacial Seneca lake. This plateau is 

 of only moderate height and slopes northward. The Northern Central 

 (Pennsylvania) railroad crosses it diagonally from Watkins to Canan- 

 daigua, and the summit of the road near Stanley is 911 feet. The West
