44 IT. L. PAIJU'iriLO — OLACfAL WATERS IX FINGER EAKES REGION 



nioviil of the ice iVoin tlie iiortlieni point of tliat ground the waters of 

 hike Newberry were hnvercd to lake Warren. 'J'he east-and-west scour- 

 ways which were made by the escaping Newl)err\' watei'S in the extinc- 

 tion of tliat lake are found, cut across the drurnlin surface, at a locality 

 five miles southeast of Canandaigua and two miles south of Ennerdale 

 station, on the Northern Central railroad. Here well marked channels 

 lie athwart two north-and-south roads. The liighest scourwa}^ is an 

 indefinite channel at the four corners, one and a half miles east of Reeds 

 corners, with an aneroid elevation of 985 feet. An excellent channel, 

 20 rods wide and truncating the south end of a drumlin.is found north- 

 ward with elevation of about 950 feet (aneroid). About one-eighth of a 

 mile farther north another good channel occurs, oO rods wide, border- 

 ing the south side of a moraine and truncating the north ends of drum- 

 lins. The elevation is about 930 feet (aneroid). These channels seem to 

 prove that lake Newberr}'- was destro3'ed by the extension of lake War- 

 ren into the Seneca basin. The volume of water drained through these 

 channels was considerable, as lake Newberiy had a large area and was 

 lowered through 100 feet of its depth. 



THE ''GEyEVA" BEACH 



In another publication* description has been made of a strong beach 

 along the west side of the Seneca valley. This was first discovered 

 above Geneva with elevation of TOO feet, and was traced north and west 

 to near Shortsville, with some evidences of the water-level as far west as 

 tlie Genesee river. Since the time of tliat publication the beach lias 

 been traced south along tlie west slope of the Seneca valley as far as the 

 Keuka lake outlet. It lies along the east side of the north and south 

 Preemption road from Geneva to near Bellona. a distance of over six 

 miles, except that north of Billsboro village the beach lies obliquely 

 across the road. It is more or less broken b3' embajnnents, but in places 

 is a heav}'' ridge. A mile from Bellona the beach swings eastward, and 

 on account of the steeper valle}^ slope it lies less than a mile from 

 the present lake. East of Bellono and three-fourths of a mile west of 

 Earles station, on the Fall Brook railroad, the beach passes beneath the 

 house and barn of Edwin Earle. South of his house it crosses obliqueh' 

 to the east side of the road and for five miles pursues a neai'l}^ direct 

 course parallel with the Seneca shore. It now becomes weaker and is 

 traceable with difficulty. A mile from Dresden it curves westward up 

 the embayment of Keuka outlet. The most southerly point of the shore- 

 line ]ihenomena of this Avater observed at this writing is near Mays 

 Mills, on the Penn Yan branch of the Fall Brook railroad. The beach
