LOWER SERIES OF KEEXE VALLEY GROUP 663 



sheet a mile east of Upper Jay Village, which cuntinues on to the Ausable 

 sheet, where we find Otis Brook flowing on the eastern edge. Here the 

 altitude is about 940 feet. 



Otis Lake (altitude, 900 feet).— Between the 935 and the 870-foot 

 levels there have been noticed a number of random beaches and terraces 

 in the valley of the East Branch, all situated at 900 feet, with no apparent 

 deformation. A beach near Keene, ill-defined terraces in the neighbor- 

 hood of Upper and Lower Jay, also give evidence of what I have called 

 Otis Lake. 



Bocky Branch Lake (altitude, 860 to 880 feet) .— Bocky Branch Lake is 

 announced on the basis of three terraces around the villages of Upper 

 and Lower Jay. The altitude ranges from 860 to 880 feet. Both the 

 outlet and the deformation are unknown; nevertheless the terraces are 

 definite .in character and rank on a par with others. 



Clifford Lake (altitude, 840 feet). — A little south of the junction of 

 Clifford Brook and the Ausable River there is a benchlike terrace formed, 

 apparently, by wave-cutting in a kame moraine of striking appearance 

 and easily seen from across the river on the State road. The height is 

 840 feet. Farther north, five-eighths of a mile northeast of Lower Jay, 

 a beach at 860 feet and the probable outlet half a mile south of Bagged 

 Mountain give an approximate deformation value of 2.60 feet per mile. 

 The river, after flowing through this pass, in all probability turned south- 

 ward through the long, narrow pass to the east of Bald Mountain. 



Styles Lake (altitude, 820 to 825 feet). — A series of terraces near the 

 junction of Styles Brook and the Ausable and to the north of the same 

 were formed by the Styles Lake. Some of them fail to line up perfectly, 

 while others roughly fit the hypothetical plane. The controlling outlet 

 channel may have been either one of two passes — the long channel east of 

 Bald Mountain or the channel 2% miles directly south of Ferrona. The 

 ice, it would seem, had retreated to allow the northern slopes of Bagged 

 Mountain to act as a one-bank channel. 



Wainright Lake (altitude, 760 feet). — Between the villages of Upper 

 and Lower Jay terraces of a glacial lake with an altitude of 760 feet are 

 observed at some distance from any appropriate geographical name. 

 Wainright Mountain is the nearest feature; hence the name. A terrace 

 and a beach, 760 and 770 feet respectively, in the vicinity of Upper Jay 

 are too near together to give any accurate figure for the deformation. 



Clintonville water level (altitude, 680 feet). — About Ausable Forks 

 and Clintonville the most impressive Pleistocene features are the almost 

 diagrammatic terraces at 680 feet. Great sandy plains stretch on both 

 sides of the river. The most striking exhibit is the level down through
