REPORT OF THE DIRECTOR AND STATE GEOLOGIST 1902 1*21 



into the gravel plain, and further artificial excavation behind 

 the station gives an unusually good section of kame or glacial 

 gravels [see pi. 3]. This section, 90 feet high above the rail- 

 road, shows coarse gravels dipping steeply southward (dip of 

 24° or more), capped by nearly horizontal beds of variable 

 material. 1 



The railroad levels make the altitude of the track at the 

 station 1172 feet. The top of the cliff is about 90 feet above 

 the railroad, but the plain is somewhat higher toward the 

 northeast, and this southern outlet of the Sauquoit waters is 

 taken as 1270 feet. 



As the surface of the Sauquoit lake was more than 100 feet 

 higher than that of the Oriskany lake on the west, the recession 

 of the ice barrier on the crest of the separating ridge allowed 

 the Sauquoit waters to escape westward into the Oriskany 

 waters. The channels cut by this westward flow, which drained 

 the Sauquoit waters away from the Richfield Junction outlet, lie 

 across the top and northwest face of Crow hill, 3 miles south- 

 east of Clinton [see pi. 2]. The highest of these cuttings shows 

 as a steep bluff between the two north and south roads. 

 Naturally the altitude is but little under that of the Richfield 

 Junction outlet, or about 1260 to 1250 feet. The two other 

 cuttings, which are on the northwest face of the hill, have alti- 

 tudes of about 1200 and 1160 feet. 



The recession of the ice front from Crow hill lowered the 

 Sauquoit waters to the Oriskany level, and of course no lower 

 channels are found here. But the wave cutting by the Oriskany 

 waters may possibly be found at about 1150 to 1140 feet on the 

 exposed northwest spur of the hill. 



This second stage of the waters in the Sauquoit valley was 

 consequently only an extension of the Oriskany lake, with outlet 

 at Bouckville. Probably this phase did not last long, as the 

 opening of still lower escape by channels southeast and south of 

 Utica drained the waters down to a stage which we may 'call 

 the Clinton lake.

 and character of this outlet.
