AREAL DESCRIPTION 627 



Westward the gromid has been smoothed at 200 to 220 feet. Nearly ail 

 the surfaces below 100 feet are sand. 



In the district of Fall River the wave-work was erosional on the hills 

 of massive and very stony moraine. The Townsend Hill, three miles 

 southeast of the city, clearly shows wave action up to 230 feet, the 

 theoretic limit. Less evident features occur on the west side of Pocasset 

 Hill. 



The evidence of the recent rise of the -New England coast is plainly 

 seen from the railroad between Providence and New London, in numer- 

 ous plains, up to height of 160 feet. The southeast portion of the 

 Kent sheet indicates deltas of south-flowing streams at the summit level, 

 210 to 215 feet. Good deltas should be found in the valley of Wood 

 River, the southwest portion of the Kent quadrangle, at the theoretic 

 levels. 



EASTERN CONNECTICUT 



All the drainage of eastern Connecticut is southward, mostly being 

 gathered into the Thames River. Numerous fillings of standing water 

 lie in the region, and are conspicuous by contact with the rough and 

 stony hills. 



Three miles northwest of New London is an excellent outwash plain, 

 locally known as the "Mile Plain," which carries the Kenyon green- 

 houses. It rises from 160 up to 180 feet. Excavations show the fine 

 horizontal bedding. Kettles occur at 165 to 170 feet, and the sharp 

 limit against the stony till is 175 to 180 feet. The marine summit is 

 about 200 feet. 



Between New London and Norwich, along the Thames estuary, many 

 elevated, but inferior, plains are seen, from 90 to 160 feet. Examina- 

 tion of the lateral valleys will discover summit plains at higher levels. 



Plains in the western part of Norwich are 100 to 120 feet altitude, 

 while the valley of Yantic River, west of the city, holds evidences of 

 standing water from 200 to 220 feet. The Norwich sheet suggests a 

 wide valley filling five miles west of the city, at Bozrah Street, in the 

 valley of Gardner Brook at 200 feet and 220 at the valley head. 



The Quinebaug River, with a large drainage area extending into 

 Massachusetts, holds very heavy delta deposits. These begin at Jewett 

 City and are heavy in the open stretches of the river valley and tributary 

 valleys to Putnam. The writer has traced them as far north as Killingly 

 (Dayville). Careful measurements will determine the summit levels as 

 about 240 feet at Jewett City, 250 at Plainfiekl, 260 at Wauregan, 275
