ful physical and chemical examination, but they will sometime 

 be found. 



The broad gravel plains west and south of Frankfort are a 

 delta plain derived from Mover creek gulf and the glacial 

 stream cuttings on Dutch and Frankfort hills. The plains seem 

 more level than shown by the map contours. Plate 12 shows 

 only the north end of the plain northwest of Frankfort, looking 

 toward the east end of Dutch hill. 



The area west of Utica in the Sauquoit valley is probably in 

 part delta material of Sauquoit creek. 



Southeast of Oriskany, extending to near Whitesboro, is a 

 broad tract of gravel which in relation to the creek should be 

 delta, but the western end, near the creek, has a high relief 

 with knolls rising to 600 feet, according to the contouring. The 

 portion lying along the river valley, about 1% miles long and 

 y 2 mile wide, is leveled at 540 feet. The present suggestion is 

 that it is partly delta and partly a kame area leveled by lake 

 or river action. Southwest of Oriskany village is another gravel 

 plain at 540 feet, according to the map. [See Oriskany sheet] 



Opposite Oriskany, on the north side of the valley, is another 

 level gravel plain, 2 miles in length, with altitude 520 feet by 

 the map. Other areas appear along the north side of the valley, 

 toward Home. The largest one is a delta plain along the west 

 side of Mnemile creek, with altitude somewhat over 520 feet. 

 The elevated tracts from 2 to 5 miles east of Rome, which on the 

 map appear similar to the gravel plains, are morainal tracts, 

 chiefly kame gravels. 



As named earlier in this paper, the standing water in which 

 these plains were built is the Utica lake, the level of which was 

 determined by the rock barrier at Little Falls; or possibly for 

 a time by a delta barrier built in the valley between Frankfort 

 and Herkimer. 



It is assumed that these plains of nearly uniform altitude (at 

 least within 20 feet) represent constructional lacustrine levels. It 

 seems quite impossible that the accordance could be produced 

 by accident to or deformation of originally discordant levels.
