PHENOMENA OF SENECA AND CAYUGA VALLEYS 47 



long cultivated fields, has disintegrated into a rather stiff soil quite unlike 

 an ordinary beach. 



The shoreline of lake Newberry passes through the village of Ovid. 

 The natural surface of the ground has been so changed that the exact 

 location and elevation of the beach has not been found. Probably the 

 main north-and-south street in the business portion of the village is near 

 the beach level, and the concave slopes of the drunilins on which stand 

 the court-house and the academy are the wave-cut cliffs. The Newberry 

 beaches will probably be found east of the academy, also southwest of 

 the village. 



It was at this point that the Ithaca lake was extinguished and the 

 waters of Watkins lake took possession of the Cayuga valle}^ thereby 

 inaugurating lake Newberry. This is discussed farther on (see page 49). 



Cayuga Valley 

 determination of water levels 



The later work in this valley has been the determination of the water 

 levels at a few localities. The highest level, that of the local Ithaca lake, 

 has not been studied recentl3^ 



The delta at Coy Glen, in the inlet valley near Ithaca, was used in the 

 former paper relying upon the Ithaca sheet of the topographic map for 

 elevations. B}^ careful instrumental leveling, using the Lehigh Valley 

 railroad as datum, the rail on bridge over the inlet creek hear the delta 

 being 393.7 feet, the broad flat terrace correlating with the Warren level 

 was found to be 865 feet elevation. Below this is another good bench 

 at 831. Other benches occur at 737 and 654, and a broken terrace 618 

 at the head down to 580 at the point. 



At Willow Creek station a small stream built some terraces at the 

 successive water-levels. Below the station of the Lehigh Valley railroad 

 is a sloping terrace with gravel ridges generall}^ parallel with the ravine 

 ending lakeward as bold spits or bluffs. These occur both sides of 

 the ravine near the house of Mr Horace Sutton, and together they form 

 an extended bluff" of gravel. Taking the rail at station as 747.62 feet, the 

 head of the gravel ridges is 622 feet, and the}' terminate at 611 feet. This 

 bluff" is regarded as indicating a sublevel of the Geneva Beach waters 

 (lake Dana). 



About one-half mile up the slope west of the station delta gravels are 

 well displa3''ed both sides of the ravine at levels marking the position 

 of Warren waters. The lower terrace underlies a vineyard on the south 

 side of the ravine opposite a tenant-house of Mr H. F. Owen. The frontal 

 bars are 825 feet and the good heavy bar at back of terrace is 829 feet
