96 Report of the State Geologist. 



The first one to be mentioned, being the northernmost, is 

 rather more than a mile we^t of Ha3^t's Corners, on a rise of 

 ground facing north, and forming a low escarpment. It is rep- 

 resented in figure 24, which is taken looking westward. The 

 impression is correctly conveyed of the level prairie country in 

 which the hill occurs. 



Ihe elevation of Hayt's Corners above mean high tide, fur- 

 nished by the kindness of Mr. Esser, Sup't of Division, Lehigh 

 Yalley R. R., is 791.3 feet. The road ascends westward for 

 a half mile, descends slightly and reascends to the same height. 

 With a hand-level the elevation of the top of the rock was esti- 

 mated at 50 feet above the station, or 840 A. T. There is a 

 chance of an error of a few feet (perhaps five), in this statement. 

 Thickness less than 11 feet, resting on Hamilton shale. The 

 upper part may have suffered loss from erosion. The rock has 

 been quarried to furnish road material. 



1 he next exposure westward is at Willard Hospital, where a 

 cascade falls over Tully limestone near the reservoir. Here the 

 contacts are perfect above and below ; thickness at fall 11^ feet. 

 The rock displays a considerable dip, east, west and south, and 

 has been largely quarried for road building. From data obtained 

 at tlae Hospital the top of the reservoir appears to be 599 feet 

 above tide ; top of quarry -rock 45 feet, less, say 564 feet. There 

 is no indication of rock in the conformation of the country 

 between these two exposures, nor between this and following 

 ones, for which we have to depend on cliff and stream exposures. 

 The thickness, measured at Highland station in creek, was 11-^ 

 feet; at Lodi, main glen, IS^; Deer Lick Run, 12 J. 



The^ rock appears at the Seneca lake front about a mile south 

 of Willard Landing. When first seen it is emerging from the 

 lake, reaching the height of 15-20 feet in one quarter of a mile 

 southward and fully displayed. The dip beneath the lake can 

 be but slight, as Hamilton shale is found 200 feet north of the 

 emergence. In the next creek (Highland station) it is found in 

 a waterfall 900 feet from the lake and 50 or 60 feet above it. It 

 caps the cliff for one-half mile, beginning some way south of 

 Highland; height, 40-50 feet. In the next deep glen it is 40 

 feet above the lake at 400 feet from the shore. At Lodi it comes 

 within a few feet of the lake level.
