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

 crops. The surface^ of tlie country has here the ixMuliar rolling 

 topography due to morainal deposits. Deposits of stratified 

 sands appear to be very raic in tlie Schoharie region, but they 

 are of marked character farther north in tlie Mohawk valley.^ 

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

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