GEOLOGY OF THE HONEOYE-WAYLAND QUADRANGLES J 



The Camillus strata are entirely covered on these quadrangles, 

 but are exposed at Victor on the Canandaigua quadrangle and at 

 Wheatland and Garbuttsville on the Brockport quadrangle. 



BERTIE (AND COBLESKILL?) WATERLIME 



The Camillus shales are succeeded by 85 to 100 feet of water- 

 limes varying in character from hard, flaggy layers to beds of 

 soft dolomite in which lines of deposition are very obscure. At the 

 top of this formation, in the vicinity of Honeoye Falls, there are 

 exposed 35 feet of waterlime, of which 3 feet 6 inches at the top 

 are in uneven layers 2 to 6 inches thick and break easily into small 

 rough blocks. It is quite probable that this stratum, which some- 

 what resembles the " bullhead " of Erie county, should be correlated 

 as Cobleskill waterlime, but no fossils are found in it. 



Next below these are 20 feet of hard waterlimes showing faint 

 lines of bedding. Some parts have no regular fracture. In this 

 vicinity, this bed has been quarried quite largely for building 

 purposes. 



The underlying ten feet of rock are flaggy and at one or 

 two horizons quite shaly. The lower beds are generally softer, 

 and in some parts shaly, but there are thin hard layers separated 

 by thin partings of black bituminous matter and heavier strata of 

 softer waterlimes that have no regular fracture. The contact with 

 the Camillus shales is not exposed on this quadrangle. 



The waterlimes are exposed along the Hemlock outlet in the 

 village of Honeoye Falls below the milldam east of the high school 

 building, and along the stream to below the Lehigh Valley Railroad 

 bridge. There are quarries in the upper beds east and west of the 

 south end of this bridge, where the contact with the Oriskany hori- 

 zon also appears. There are good exposures of forty feet of the 

 upper beds along Spring creek two miles west of Honeoye Falls, 

 and in the large old quarry one-fourth of a mile south of the New 

 York Central Railroad bridge over this stream. 



There is a small exposure of waterlime near an old limekiln one 

 and one-half miles west of Spring creek with the Onondaga 

 limestone five feet higher, and small outcrops of this rock occur in 

 the bed of Stony brook at Five Corners. 



In the central part of the State and in Erie county the waterlime 

 beds contain fossils of several species, but the strata exposed on 

 this quadrangle are almost barren. Leperditia alta (Con- 

 rad) and Whitfieldella laevis (Whitfield) are the only 

 forms observed.
