was the lowest point of discharge to the south of glacial confined

 fallen short of this col." (Woodworth, 1905, p. 198.) 



Evidence 



At the foot of the great Phillips moraine that lies against the 

 southeast face of Bulwagga mountain there is a broad, level terrace 

 at 350 feet altitude (United States Geological Survey). On it stand 

 J. Phillips's house and outbuildings. This terrace consists of light 

 sandy loam. It curves around the hill to the southward almost as 

 far as the Gage house, which is built on the same level. Below this, 

 to the south, lies a rather extensive plain at 300—350 feet (on the 

 contour map). It is crossed by the Russell Street road and several 

 farmhouses stand on it. The soil is a sandy loam, but it is underlaid 

 by clay. This loam deposit marks the bed of this phase of the glacial 

 lake. 



The road from Factoryville to Port Henry climbs the west end of 

 Indian ridge at a place known locally as " Leland hill." A new 

 grade cutting on this hill, made in August 1913, between the 200 

 and 240 foot contours showed an instructive section. The surface 

 of the hilltop plain at this point is composed of a layer of argillace- 

 ous sandy loam about 2^ feet thick containing a few small, erratic 

 stones. Underneath this is a layer of stratified clay about 6 feet 

 thick. It is devoid of stones and lies conformably on top of a 

 stratum of stratified fine sand. The altitude here (241 feet A. T.) 

 removes it above the range of the marine occupation. These sands 

 and clays, then, must have been deposited on the bottom of one of the 

 higher water bodies, since they are not, evidently, ground moraine. 

 The till sheet probably lies at a depth of 100 feet or more beneath. 

 The presence of scattered erratics so far from the ancient shore 

 can hardly have been due to transportation by stream currents. 

 They may have dropped from floating icebergs. This must have 

 occurred, if at all, during the latest, or Fort Edward, stage of the 

 glacial lake, as the stones lie in the top layer of soil and not in either 

 the clay or the layers of sand beneath it. 



On the hill west of Factoryville a barometric reading was taken 

 at 331 feet where a terrace has been cut into the hill, apparently by 

 wave action, just below its top. A sample of soil taken from this 

 terrace consisted of fine sand; and a few small stones were found 

 about here in the level field.
