let between the 480 and 500 foot contour lines. This lakelet 

 probably owes its existence to a remnant of ice on the north, 

 separated from the Fort Edward mass during the stagnation 

 of the ice south of the mountain passes. The nature of the 

 bottom of the lakelet has not been determined but presumably 

 there is bed rock close underneath. Both clays and bed rock 

 appear eastward near West Fort Ann village in an extension 

 of this ridge. 



West of this outwash deposit and north of Queensbui'y vil- 

 lage, there is developed between the 420 and 440 foot contours 

 a deposit having in its highest part, where it confronts the 

 northwestern margin of the Patten's Mills terrace, a large 

 depression or kettle hole, shown by the contours on the Glens 

 Falls sheet [see pi. 14]. This depression also sho^^s that ice 

 remained on the northern side of the Patten's Mills deposit in- 

 dependently of the evidence afforded by the small lakelet, and 

 renders it probable that the slope of the ground in that vicinity 

 from the 480 down to the 440 foot line is also an ice contact 

 feature. 



Morainal terrace at North Argyle. About 1 niile east of the 

 village of North Argyle on the Fort Ann quadrangle is a rock 

 ridge culminating in a point 1037 feet above the sea. The ridge 

 extends northeast and southwest. At its western base over- 

 looking the Fort Edward district from the east is a terrace 

 of glacial till rising over 120 feet above the low ground at its 

 base and having a maximum elevation at the summit of about 600 

 feet. This terrace appears to have been deposited by live ice 

 and presumably is of somewhat earlier date than the stratified 

 deposits found elsewhere on the north and west at somewhat 

 lower levels. 



North of Evansville in a similar position in relation to an 

 older rock ridge and in nearly the same alinement a till ter- 

 race rises from the west bank of the Moses kill with its mass 

 between the 500 and GOO foot contour lines. 



None of these deposits afford other clues to the level of the 

 waters which may have stood in this district subsequent to the dis- 

 appearance of the sheet than by their negative character-^the 

 absence of later clnvs nnd wave marks over their surface. Tt
