vicinity of the river. A broad shelf at this level borders the 

 Moses kill where that stream enters the Hudson gorge. In such 

 cases the drift deposit may well depend on the bed rock for its 

 position. 



The erosion forms of the Batten kill delta along the bank of 

 the Hudson opposite Schuylerville form a conspicuous feature in 

 the landscape and the topograjjliy of this side of the river is in 

 strong contrast to the west bank on which the delta sauds appear 

 in the vicinity of the Saratoga Battle Monument. 



The clays which underlie the delta appear throughout the 

 district below the 300 foot level. 



Durkeetown terrace [see pi. 12]. One mile south of Durkee- 

 town in the northeastern corner of the Schuylerville quadrangle 

 a ridge rising above the 300 foot contour line extends south- 

 south west ward for IJ miles, bounding the Fort Edward district 

 on the southeast. On the western slope of this ridge between 

 the 280 and 300 foot lines is a weakly developed terrace of water- 

 worn gravels. These are coarse cobbles on the northeast above 

 the road but become fine gravels toward the southwest at the 

 crossroads. The general appearance of the deposit is that of 

 a beach on which the materials have traveled southwestward. 

 There is nothing in the frontal slope of the narrow terrace to 

 prove that the margin of the ice remnant lying over the Fort 

 Edward district confined the deposits as in the case of many 

 likewise narrow terraces at higher levels along the base of 

 the mountain on the west of the same district. The terrace 

 may be taken therefore as the index of water level during the 

 closing stages of the deposits of the Albany clays when the ice 

 had melted out at least as far north as this locality. On the 

 east of the same ridge is a flat floored valley at about the same 

 level, one which corresponds with the upper limit of the clays 

 over the western part of the Fort Ann sheet on the north and 

 with the outward margin of the delta of the Mettawee at West 

 Granville. 



Fort Edward district. At the northern border of the Schuyler- 

 ville quadrangle the rock terraces of the Hudson gorge retreat 

 east and west, and the gorge widens out into a depression trav- 

 ersed by the present but newly established course of the Hud-
