e mouth of Wood Creek are four tributaries: (1) 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.
1). 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 1-3/4 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.[7] It is probable 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.

[Footnote 7: 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.]

The level obtained at No. 8 is from a hole drilled within 50 feet of
the river. The drill struck rock at an elevation of 316 feet after
passing through 69 feet of quicksand, gravel, and till. This is
clearly not within the channel as it is quite impossible to reconc
