Lake George directly into Lake Champlain. Some of these are largely, 

 if not essentially, preglacial in their courses, occupying the earlier 

 valleys mentioned above. Others have been obviously influenced in 

 their present locations by the glacial deposits. It is clear from the 

 insuperable rocky obstacles presented that drainage must even in the 

 preglacial period have radiated from the central height of land, and 

 that there is a marked preglacial divide around Mt. Marcy which at 

 this time separated the waters going north from those going south. 

 But there are some strange features about the present courses of the 

 Hudson and Sacondaga and some interesting points about Lake George 

 which will be briefly noted.

 Utica slates, from flatness on the left beyond the picture, are dragged to a fairly steep inclina- 

 tion, where faulted against the hard Beekmantown limestone, which lies several hundred feet 

 below in the stratigraphic series. 



The Hudson gathers its waters first from a series of beautiful 

 mountain lakes almost under Mts. Marcy and Mclntyre, the loftiest two 

 peaks, and flows nearly due north for fifteen miles, following, no doubt, 

 one of the older north and south valleys. It then turns abruptly 

 westward, winding for five miles amid hillocks of drift, and tapping 

 a notable series of east and west lakes near Newcomb village, doubt- 

 less impounded in one of the old east and west valleys. It then turns 

 nearly due south for ten miles and makes an abrupt bend, of somewhat 

 less than ninety degrees, to the eastward, being apparently diverted 

 into an east and west valley by a barrier of drift. Just after it makes 

 the turn it receives the waters of Indian Eiver coming from a drift-
