No. 3O.] ROCKY RIVER. 23 



miles, there are no distinct tributaries. South of the mouth 

 of Wood Creek are four tributaries: (i) the brook which enters 

 the valley from the west about one mile south of Neversink 

 Pond, (2) Balls Brook, which empties into Neversink Pond, and 

 (3) two streams on the east side Mountain Brook and one 

 other unnamed (fig. i). All these, except Mountain Brook, are 

 normal to the reconstructed drainage. The evidence of the 

 tributaries, though not decisive, is thus favorable to the hypothesis 

 of reversal. 



THE BURIED CHANNEL 



Figures 3 and 5 show what is known of the buried channel of 

 Rocky River. The only definite information as to rock levels is 

 that derived from the drill holes made by R. E. Dakin for the J. 

 A. P. Crisfield Contracting Company in connection with work on 

 a reservoir for the Connecticut Light and Power Company. 

 Numerous holes were drilled at the points indicated on fig. 5 as 

 No. 8, D, J, No. 7 + 1000, and No. 7, but only those showing the 

 lowest rock levels need be considered. In the following account 

 the elevations quoted are those determined by R. E.-Dakin which 

 differ, as shown in fig. 3, A, from those of the New Milford atlas 

 sheet. 



Between the mouth of Wood Creek and Jerusalem bridge 

 holes made near the river show that the depth of the drift 

 chiefly sand, gravel, and clay varies from 45 to 140 feet. The 

 greatest thickness of drift, consisting of humus, quicksand and 

 clay, is 140 feet at a point 20 feet from the east bank of Rocky 

 River and about ij4 miles north of the mouth of Wood Creek 

 (fig. 5, D). Although some allowance should be made for glacial 

 scouring, the rock level at this point, 244 feet, is so much lower 

 than any other record obtained between this point and Danbury 

 that one is obliged to assume a buried channel with a level at 

 Danbury at least 75 feet below the rock level found in the lowest 

 well record. 1 It is pro'bable that this well is not situated where 

 the rock is lowest, that is, it may be on one side of the old Still 

 River channel. 



1 Well of J. Hornig, rear of Bottling Works, near foot of Tower Place, 35 ft. to 

 rock, indicated at a, fig. 5. The well of Bartley & Clancey, 94 White Street, 70 ft. 

 to rock, is also indicated at b, fig. 5.
