the town site. Fairchild states that the correlation of the Geneva beach 

 with the Cedarvale channel is still theoretical, but that the knowledge of 

 the problem, together with the aid of the topographic sheets, is sufficient to 

 give great confidence in the accuracy of this correlation. He remarks 

 further that Lake Dana existed perhaps a century, or several centuries; 

 yet, as compared with Lake Warren, it had a brief life. 



There is but one place in western New York where the writer has 

 noted evidence of a shore at the Lake Dana level. A gravel deposit at 

 West Seneca, south of Buffalo, which seems to be the product of lake waves, 

 stands about 180 feet below the level of the Forest beach, and is theoretically 

 a continuation of the Geneva beach. It follows the crest of a narrow ridge 

 which rises just above the 620-foot contour, while the lower of the two 

 beaches on the neighboring part of the shore of Lake Warren, as shown 

 by the Buffalo topographic sheet, stands near the 800-foot contour. This 

 observation was made in 1893, before Fairchild had found the Geneva 

 beach, and the ridge was traced only about a mile, as it appeared at that 

 time to have little significance. 



In this connection the " Lundy beach" of Spencer shoidd be con- 

 sidered, since it stands near the level of Lake Dana. The name Lundy 

 beach was applied by Spencer some years ago to gravelly deposits found 

 on the borders of the Erie Basin at a level 140 to 155 feet below the 

 Forest beach, which seemed to him to mark the shore of a lake.^ These 

 deposits are fragmentary, and the interpretation of shore phenomena seems 

 open to question at several of the places cited by Spencer, if not at all of 

 them. In view of this uncertainty, and also because the level seems to be 

 25 to 40 feet out of harmony with the Geneva beach, it hardly seems 

 advisable to cite the "Lundy beach" as a feature of Lake Dana. 



Faint beaches have been noted in western New York at levels still 

 further out of harmony with Lake Dana. About 4 miles south of West 

 Seneca, on a bluff back of Bay View, a cut bank was found at a level 60 

 feet higher than the gravel deposit at West Seneca, the altitude being 

 above the 680-foot contour. This bank, which has also been observed by 

 Taylor, apparently marks a temporary shore of the lake, yet it harmonizes 

 in altitude with neither the Geneva nor the Lmidy beach. 



A few miles farther south, at North Evans, on the south bluff of Eight-
