feet, and other water planes at 1400 to 1600 feet. For these waters 

 he proposed the name Lake Adirondack. 



As these waters must have been extremely disconnected, lying 

 at dififerent levels about the margin of the exposed highlands, and 

 tributary to those on the south side with ultimate escape across the 

 ice strait in the Mohawk valley, the writer hesitates to call them 

 by a name implying a distinct lake. However, the name Adirond.ack 

 waters holds both by priority and appropriateness. 



The existence of standing waters in the larger Adirondack valleys 

 has also been recognized by I. H. Ogilvie (see title 29), but no 

 altitudes are given. 



It is not possible now to locate with absolute confidence the point 

 or points of outflow, or the valley south of the divide which carried 

 southward the glacial waters. It was not necessarily by the stream 

 which today has the lowest col on the divide between Mohawk 

 and Susquehanna drainage, and there might have been more than 

 one point of escape. 



The col at Cassville and Richfield Junction (Delaware, Lacka- 

 wanna & Western Railroad) 10 miles south of Utica, has a com- 

 bination of characters that are suggestive in this connection (see 

 plate 5). Here is a smoothed col, over a mile wide, heading at 

 about 1260 feet the wide, smooth valley at North Bridgewater now 

 drained by the west branch of the Unadilla river. A broad sand 

 plain north of the railroad junction has the altitude of the col and 

 indicates standing water north of the divide. A kame-moraine 

 area north and west suggest a long stan,d of the ice margin at this 

 place with heavy outwash. This pass could not have been the outlet 

 of widespread or open Mohawk waters as the Cedarville pass, six 

 miles southeast, is 40 feet lower. The writer has supposed (see title 

 17, page 20) that the glacial waters of the Sauquoit valley were 

 responsible for the characters of this pass, but they hardly seem 

 competent. The pass at Bouckville, the head of the Oriskany valley 

 at 1 150, is also suggestive, but it lies far Avest. Another pass which 

 certainly carried a flood of water is the col at the head of the Otsego- 

 Susquehanna valley with altitude 1360 (described page 23). If 

 this outlet did not carry the earliest flow from the Adirondacks 

 across the ice strait it certainly did carry glacial waters before 

 the Cedarville pass was opened. It has also the location opposite 

 what would seem to have been the weakest section of the Avaning 

 ice strait. 



The ice in the valley may have been so heavily burdened with rock
