PHENOMENA OF SENECA VALLEY 45 



seems to pass beneath the house occupied by Mr Ezra Decker, and in 

 the field in front of the house is a strong bar on a delta parallel with 

 the creek. Taking tlie railroad at Mays Mills as datum at 556 feet, the 

 elevation of the bar is 650 feet. Three miles north, near Angus station, 

 the bar is 671 feet, using the railroad datum. About three miles farther 

 north, at Mr Earle's,the well formed beach of apparently full height is 679 

 feet. About seven miles farther north, at Geneva, the full height of beach 

 by Mr Bean's, on the Preemption road, is 700 feet, taking as datum the 

 top of rail of the Lehigh Valley ti-ack crossing of the Preemption road as 

 606.92 feet. By the same railroad datum, using the rail at Phelps as 

 600.82, the heavy bar at the reservoir of the Phelps water works, five and 

 one-half miles northwest of the last point, is 713 feet. 



Careful research will undoubtedly reveal the Geneva beach farther 

 south in the Seneca valley. This beach is now correlated with an out- 

 let at Marcellus, and the water is named lake Dana (see page 56). 



EAST SIDE OF SENECA VALLEY 



At Burdette, about one-half mile west of the railroad station and just 

 west of the village, the Newberry shoreline is found at the head of the 

 steep slope, on the north side of the ravine. The highway is crossed by an 

 irregular kame-like ridge in which is a gravel pit on the south side of 

 the road. Southward from the gravel pit the ridge is a good bar. Pass- 

 ing by a till knoll as a shelf or cut terrace, and then curving around to 

 the west parallel to the ravine, it rapidly descends and ends as a very 

 bold spit facing the valley. An old cemetery is located upon the ex- 

 treme point of the s\nt. Behind the bar, near the road, is a broad kettle 

 basin. 



Taking as datum the Lehigh Valley railroad at the station as 1,001.62, 

 the elevation of the bar is 964 feet. This is thought to represent nearly 

 the true water-level. 



The slope of the valle}' is so steep that the formation of shore deposits 

 at lower levels was not favored, and the Warren shoreline is not found 

 at the theoretical level. Somewhat lower, however, is a terrace in the 

 delta with a bar front having elevation of 828 to 832 feet. 



Below this the slope is precipitous, and the Geneva beach is not shown. 



Upon the south side of the ravine a distinct bar lies at an elevation 

 (aneroid) of about 935 to 940 feet. 



At Hector station the Newberry shoreline is above the railroad. Tak- 

 ing the rail as 919.52, the bar on the south side of the highway. on land and 

 close to the house of Mr A. B. Nivison, is 976 feet elevation. This is 

 on the north side of the ravine. Higher up the delta is another ridge at 

 elevation of 990 feet, behind which is a large and deep kettle. This bar
