accomplished by the streams. The deposits of till or ground 

 moraine which were left in portions of the valley bottoms and 

 which now serve as sites for cemeteries, constitute the chief 

 topographic features due to the ice. On the upland this deposit 

 of ground moraine is very characteristic and in the region be- 

 tween Central Bridge and Cobleskill it mantles most of the out- 

 crops. The surface of the country has here the peculiar rolling 

 topography due to morainal deposits. Deposits of stratified 

 sands appear to be very rare in the Schoharie region, but they 

 are of marked character farther north in the Mohawk valley. 1 

 The direction of the glacial striae and furrows on East hill were 

 found to be n.50°e., and on Woman's Xose n.80°e. [Prosser].
