Weatherwax quarry is N30°E and at the southern end of the gorge 
N between 40° and 41° E. 
There seems to be no published estimate of the throw or amount 
of displacement of this fault.. If the thickness of the Utica slate 
along the line of the fault be as great as it appears to be south of 
Amsterdam, six miles to the west, then it must amount to some 
1600 feet; since it would comprise the 1440 feet of the Utica slate 
and the footwall of Calciferous sandstone 150 feet or more in hight. 
SARATOGA COUNTY 
Rock City falls section 
At Rock City or Mill on the Kayadarosseras creek, six miles: 
west of Saratoga Springs is an exposure from the upper part of the 
Calciferous sand rock well into the Trenton limestone. The section 
is as follows: 
Feet 
12H! Massive Calciferous sandrock forming the 
falls. There are rolls in the upper part of the sand- 
stone, and the top of the Calciferous on which the Vee tea) 
superjacent limestone was deposited is irregular. 12412} 
H? Light dove colored limestone in which are a 
few - small vertical fucoidal markings, probably 
Phytopsis tubulosa. Birdseye limestone. I=134 
H? Texture similar to that of H? but most of the 
fucoidal markings are irregular, lateral shaped to 
horizontal. In the end nearer the creek, however, 
there are a few vertical markings which extend to the 
top of the 2 feet, 10 inches of dove colored, compact 
limestone. This stratum probably belongs in the 
Birdseye. 3 13153 
H* Thin bedded, blocky limestone which is a sort | 
of transitional Black river limestone. I=16} 
H® Thin bedded Trenton limestone extending to 
the top of the cliff and containing plenty of specimens 
of Rafinesquina alternata (Con.) Hall and hye 
Clarke associated with other fossils. | 8425 
H® Thin beddef limestone which becomes more Yea 
massive in the upper part. 374 feet of Trenton lime- 
stone exposed. | 29—=54
