nearly 4 miles up the Hudson from Warrensburg. It is here pro- 

 posed that this whole long, narrow, remarkable, now extinct, post- 

 glacial lake be called Lake Warrensburg. Professor Stoller's Lake 

 Corinth, described^" in his report on the Saratoga quadrangle, is 

 believed to represent the southern end of Lake Warrensburg. 



The level of Lake Warrensburg was maintained by the wall of 

 the retreating Hudsonian ice lobe which reached across the Hud- 

 son valley a few miles east and south of Corinth. The outlet of 

 the lake was between the ice on the lowland and the western high- 

 land near South Corinth where theie is a pass leading southward 

 to the valley of Kayaderosseras creek whose valley, as Fairchild 

 says, " shows excellently the work of a short-lived river of high 

 gradient and large volume." After the outlet was cut down to the 

 636-foot level at South Corinth, the ice blockade across the Hudson 

 valley east of Corinth disappeared and Lake Warrensburg was soon 

 lowered to extinction because the outlet east of Corinth was lower 

 than that at South Corinth. 



An arm of Lake Warrensburg probably extended several miles 

 up the Sacandaga valley, though quite certainly not beyond Conk- 

 lingville because even the present flood-plain of the river from that 

 village westward lies at too high a level (720-40 feet) to correlate 

 with the terraces of the Hudson valley, and distinct delta deposits 

 and small sand flats rise to still higher levels or up to 770-80 feet, 

 as at Day Center. It would seem that the standing water in which 

 these deposits accumulated formed part of Sacandaga lake which 

 flowed into Fairchild's Amsterdam lake through a pass at 760 feet 

 a few miles southeast of Gloversville. Before a valid conclusion is 

 reached in this matter, the lake deposits of the Sacandaga valley 

 should be carefully studied. In any case the Sacandaga lake waters 

 seem to have been held up by the wall of the retreating glacier 

 across the Sacandaga valley somewhere in the vicinity of Conk- 

 lingville, probably east of the village. Removal of the ice dam 

 would have allowed movement of the Sacandaga waters eastward 

 into the lower level Lake Warrensburg. Since the Ice Age the 

 Sacandaga river has cut away most of the lake deposits to a depth 

 of at least 40 to 60 feet, while from Conklingville eastward to its 

 mouth the very swift Sacandaga has accomplished much more work 

 of erosion. 



Beds of small higher level extinct lakes were observed at a num- 

 ber of places. One of the best is the sand flat area covering nearly
