Along the road leading from Watkins to Montour Falls on the 



west side, there appears a mile north of the latter place, a compact 

 sandstone 2 feet 4 inches thick, abundantly exposed toward the 

 north, that is the most prominent feature in the stratigraphy of the 

 lower rocks of this quadrangle. 



At the south end of the exposure it is 450 feet A. T. and nearly 

 level, but it soon rises toward the north and at the mouth of Watkins 

 glen it is exposed at 480 feet A.T. The top of the anticline is reached 

 about opposite the railroad station at Watkins at 490 feet A. T. 



Thence northward it descends rapidly and disappears under the 

 water of the lake % mile north of Salt point ; after sinking to about 

 25 feet below the lake level it rises again and emerges on the south 

 side of Corbett point and continues to rise to Fir Tree point where 

 it is 72 feet above the lake; thence it descends and reaches the lake 

 level again near the north line of the quadrangle. There is an 

 eastern dip of about 25 feet to the east side of the lake and the undu- 

 lations are not so apparent except for 2 or 3 miles at the head, the 

 strata farther north being covered to a large extent. 



In the vicinity of Elmira there is a strong western dip. In the 

 quarry at Pine City it is at the rate of 25 feet a mile, in the quarry 

 1% miles west of Southport, 130 feet a mile, and about the same 

 at the south end of the bridge over the Chemung river 2 miles south- 

 west of Big Flats. At the mouth of Latta brook ravine it is 22 feet 

 a mile. In the shale quarry 1 mile northeast of Horseheads the strata 

 descends toward the west at the rate of 75 feet a mile.
