streams into the sea or into the temporary lakes that abounded 

 over the land surfaces during the glacial period. 



In order to test this hypothesis it was necessary to seek some 

 point where the details of a Kame system could in some way be 

 submitted to criticism. Such an opportunity presented itself 

 to me in a remarkably fine system, as yet undescribed, which 

 lies in one of the broad valleys of the southern Adirondacks in 

 which stands the village of Chesterton,Warren County, New York. 

 This valley is the southward continunation of the basin in which 

 lies Schroon Lake and the upper part of Schroon River. At a point 

 about two miles to the north of Chesterton the Schroon River turns 

 to the eastward and pursues its southward course to the Hudson 

 in another valley parallel to that in which it has its origin. The 

 result is that the Chesterton portion of the Schroon valley opens 

 broadly to the north, while on the south it narrows and rises to 

 a col or divide, which is nearly three hundred feet above the 

 Schroon River and about six miles from where that river turns to 

 enter the valley in which it runs in the southern part of its 

 course. An inspection of the glacial scratches makes it clear 

 that during the closing stages of the last ice period the direc- 

 tion of the glacial stream did not turn to the eastward as the 

 river now does, but pursued its course directly up the valley and 

 over the col at its south end and by that route to the lower por- 

 tion of the Schroon Valley and thence to Lake George. Where 

 now the small stream in the village of Chesterton flows northward 

 down a tolerably steep slope to join the Schroon River the ice 

 flowed up hill in its southward course. At its northern point 

 the Chesterton Kame is first evident t in the swamp that occu- 

 pies the valley of the southern end of Schroon Lake. It then grad- 

 ually rises from the level of the swamp, which has evidently ac- 

 cumulated about it to a depth of ten to thirty feet. Where first 

 traceable the ridge is not over twenty feet high. I am not certain 

 that I saw the very northern most part of the Kame for the reason 

 that the swamp was at the time of my examination so wet that it 

 was extremely difficult to explore. There may be parts of the 

 ridge above the level of the swamp for two miles north of the 

 northernmost point examined. 



At the northernmost position where the Kame is fully exposed 

 and thence for about six miles near to its southern end it consists
