REPORT OF THE DIRECTOR AND STATE GEOLOGIST

Hill did not happen to see this, and we have no farther details 

 to add to the previously published description. 1 



The glacial and post-glacial deposits and the recent geologic 

 history of this town are of surpassing interest, but they have 

 not been sufficiently studied by us to be described at length. 

 It is evident that Lake George once penetrated much farther 

 up the depressed valleys than it does today, and that to it is 

 largely due the great accumulation of sands. In the rearrange- 

 ment of the drainage systems following the close of the glacial 

 period some very peculiar situations have sprung up. Halfway 

 creek, for example, has its rise in Luzerne mountain and flows 

 eastward over the sandy plain, being at one point less than 2 

 miles from the Hudson. It then strikes away off to the north- 

 east, crosses Fort Ann and discharges into Wood creek and Lake 

 Champlain. To what extent the glacial and post-glacial depos- 

 its have modified earlier relations between Lake George and the 

 Hudson is a subject demanding very thorough study. 2 



Warrensburg 



Our work in Warrensburg has only been of a very fragmentary 

 character, and we must await the issue of the U. S. geological 

 survey map of the quadrangle south of the Xorthcreek sheet to 

 give us a satisfactory base of observations. The town is a 

 long and narrow one. In the extreme from north to south it is 

 about 16 miles. As a maximum it is 6 miles from east to west, 

 but at the village of Warrensburg it is scarcely more than 2. 

 The town is divisible into two sharply contrasted parts. The 

 northern lies between the valleys of the Schroon and Hudson 

 rivers and is a blunt wedge of hilly country, whose highest 

 summits are between 1600 and 1700 feet above tide, and about 

 1000 above the rivers. The wedge is about 10 miles from 

 north to south. The southern part is not such a sharply marked 

 topographic unit, but consists of the western slopes of the ridge 

 which forms the divide between the Hudson and the head of
