The detritus washed out of the glacier into the Warren and Dana 

 waters seems to have been deposited as kames or indefinite forms, 

 and may not be readily distinguished from deposits of the pre- 

 ceding waters. The Pinnacle kame moraine probably was deposited 

 in sub-Dana waters [pi. 15-17] escaping by the Victor channel. 



The Warren and Dana planes on the Baker-Turk hills lie about 

 20 feet higher than to the southwest, or at 900 and 720 feet. The 

 cause of this greater altitude is not fully determined but is partiy 

 due to the northward position. 



Cayuga depr ssion: Clyde channels 



Between Clyde and Weedsport lies the axis of the broad north 

 and south depression which holds Cayuga lake. On this parallel 

 the lowest parts of the depression are occupied by the Montezuma 

 marshes, the western branch of which appears on the map. plate 3. 

 Savannah is situated on an islandlike drumlin group between the 

 two branches of the marsh. 



The swamp and its streams have an altitude of about 380 feet, 

 which is 20 feet under the passes on the east and west. In con- 

 sequence of this depression the stretch between Clyde and Jordan 

 must have been covered by shallow lake waters during the time 

 when glacial currents swept through the passes at 400 feet. As no 

 positive stream cutting of the latest ice border drainage can be 

 mapped between Clyde and Jordan the entire Weedsport sheet is 

 omitted from our plates; but its insertion between plates 3 and 4 

 makes the plates a complete map of the belt from Batavia to 

 Oneida. 



The low areas and somewhat irregular passes in the stretch 

 from Palmyra to Syracuse, having both north and south and east 

 and west directions, must have been in existence before the episode 

 of the latest glacial drainage, which we are studying. In some 

 places, specially where the latest ice work had partially blocked 

 the former passes, the later drainage work can be distinguished. 

 On the meridian of Clyde the map indicates three later channels. 

 Close and detailed study of the district may modify this map, 

 and perhaps find other evidences of the later ice border drainage 

 work. 



The swamp grounds in this region received the moderate volume 

 of detrital matter which was carried by the rather sluggish drain- 

 age, and a few tracts which can be regarded as at least partly 

 delta are designated on the map. The larger deltas are at
