DESCRIPTION OF SECTIONS 33 



A. — The western clay pit. 



The clay rests on till. The 150 lowest varves have slidden 

 away. Many zones are disturbed. The clay, in some zones, 

 is exceedingly fat and has been squeezed, so that the 

 thicknesses of many varves are unreliable. Consequently 

 my measurements are valueless. 



Series measured: (7100-about 7300). 



Beside this a series of 150 varves, containing 3 thick 

 slidden zones; these varves not connected with the 

 standard curve. 



B. — The eastern clay pit. 



The clay is so disturbed that no part of my measurement 

 can be connected with the normal curve. It contains 

 several beds of till which may have slidden down from the 

 hill that rises just behind the section, or may have been 

 brought there by icebergs. 



79. — i mile N of Woodsville, ravine E of the road. The lowest 

 varves were measured 200 yards SE of the ravine. 

 Weathered clay. 



Silty clay with very distinct lamination, varves 7200-7262. 

 Blue-gray clay, exceedingly fat, almost like green soap, 



varves 7147-7199. Thicknesses of varves not good. 

 Fat clay with good lamination, varves 7045-7146. 

 Silty clay with perfect lamination, varves 6967-7044. 

 Fine sand, varves 6954-6066. Varve 6954 is probably bottom 



varve. 



Series measured: 6991-7146, 7199-7262, (6954-6990, 

 7147-7199). 



80. — 2}4 miles NNW of Woodsville, bluff on the eastern side of 

 the Connecticut River, directly opposite Long Meadow 

 Farm. 



25 feet sand. 



Good varve clay, though with several disturbed zones and 

 one or two zones wholly missing without leaving any trace 

 in the section. 

 Talus reaching 20 feet down to the river. 



Series measured: 6992-7131, 7154-7177, (7200-7209, 

 7215-7227,7253-7302).
