LUZERNE RIVER 185 



daga did not have its present course past Conklingville. It now remains 

 to describe an important pre-Glacial stream (now extinct as such), which 

 did drain most of the area of the Luzerne quadrangle. This stream, 

 which the writer would call the Luzerne Eiver, had its source on the 

 south side of the Stony Creek divide and flowed southward past the vil- 

 lages of Luzerne and Corinth. As far as Corinth it occupied almost 

 exactly the same course as the present Hudson. From Corinth it passed 

 southward through the broad Paleozoic rock valley (now occupied by 

 Kayaderosseras Creek) and to the west of Saratoga Springs. Beyond 

 this its course has not been traced on account of the heavy drift. 



Wrighf showed that in pre-Glacial time no stream crossed the Luzerne 

 Mountain between Corinth and Glens Falls, and with this view the writer 

 is in perfect accord. However, in Wright's paper, the pre-Glacial divide 

 at Stony Creek was not recognized, and hence it was quite naturally as- 

 sumed that the pre-Glacial Hudson flowed past Luzerne and Corinth and 

 thence southward through the Kayaderosseras Valley. Wright explains 

 the passage of the Hudson across Luzerne Mountain as due to heavy drift 

 filling south of Corinth, and the writer believes that this explanation, 

 which is practically the same as that given to account for the deflection 

 of the Sacandaga, is certainly correct. The important point of difference 

 between Wright's paper and the present one is that the pre-Glacial Hud- 

 son did not flow southward across the Luzerne and Saratoga sheets, but 

 that the now extinct Luzerne Eiver rising on the Stony Creek divide took 

 this course. 



A pre-Glacial divide was somewhere near Spiers Falls dam, which is 

 about 4 miles below Corinth on the Hudson, and a short westward-flowing 

 stream from this divide was tributary to the Luzerne Eiver near Corinth, 

 while an eastward-flowing stream emptied into the pre-Glacial Hudson. 



A short tributary of the Luzerne Eiver flowed eastward from the 

 Conklingville divide. 



Glacial Lake Warrensburg 



This extinct lake, here described briefly for the flrst time, has a certain 

 important bearing on the drainage history of the region. The lake has 

 been so named because of the location of the village of Warrensburg on 

 the old lake deposit, which is especially well shown as a flat-topped sand 

 area between the village and the Hudson Eiver. The concordant altitudes 

 of the sand flat where unaffected by subsequent erosion, the remarkable 

 freedom of the surface from boulders, and the crudely stratified character 

 of the material as shown in cuts, all afford conclusive evidence for static
