GYPSUM DEPOSITS OF NEW YORK 5 1 



It seems probable that large quantities of gypsum as yet uncov- 

 ered must lie near the surface in Genesee county. They are likely 

 to be found from Fort Hill westward throug^h South Byron and 

 Newkirk to Oakfield, north of the limestone escarpmtent; thence 

 following the escarpment in a westerly direction to Alabama and 

 southwesterly to Akron. There is also room for development to 

 the south of the outcrop O'f the dolomites, but these areas comsti- 

 tute a reserve fo-r the future after the exhaustion of the beds near 

 the surface, 



Erie county 



Entering Erie county at a point 2 miles northeast of Akron 

 the escarpment formed by the Onondaga limestone and underlying 

 waterlimes passes through Akron southwesterly to Clarence, thence 

 we'Sitward parallel to and Vo mile north of the Clarence-Williams- 

 ville road. It continues through Williamsville and follows rather 

 closely the road from Williamsville to Buffalo. Within the city 

 of Buffalo its limits are as follows '} 



It follows the general direction of Main street from the Alms- 

 house to near the New Yo.rk Central Railroad belt line at Rodney 

 and Fillmore avenues. After crossing Main street, it passes near 

 the corner of Oakwood and Woodward to Oakwood and Parkside 

 and enters the park at the stone cjuarry, crossing from there inito 

 the cemetery at the corner of the iron fence near Agassiz place. 

 From here it sweeps around in a curve to Scajaquada creek at Main 

 street bridge and passes out of sight beneath the drift on the left 

 bank, about 300 feet below the bridge. 



Of the escarpment Bishop says : '' The hydraulic limestone is 

 usually visible at the base, or north side, of this escarpment as a 

 stratum of variable thickness in the face of the cliff but occa- 

 sionally forms a terrace ranging from a few feet to 200 yards in 

 width and approximately parallel to the escarpment. This terrace 

 is most conspicuous between Williamsville and the Buffalo city 

 line." 



Very few exposures oi the Salina shales north of the escarp- 

 ment are recoirded. The area is very flat and uniformly drift- 

 covered. A small outcrop on the southern end of Grand Island 

 and an outcrop along the Canadian bank of the Niagara from near 

 the International bridge to a point opposite Strawberry island sh5w 

 the Camillus shales to be '' soft light gray or olive gypseous 

 shales." - Borings would seem to indicate an absence of the Ver-
