SILVER LAKE. G 6 . 85 



small areas where the streams have trenched through them 

 into the top of the Chemung, in the extreme northern por- 

 tion ; but even if any such patches exist above drainage 

 they are very small and of no importance. 



The massive cliff sandstones of the Catskill are seen ex- 

 tending in long lines of vertical walls around the sides and 

 summits of many hills. One at about 600' above the base 

 of the Catskill is especially massive. This is seen capping 

 the hill at the eastern line of the township near Mr. Maro- 

 ney's at an elevation of 1795' A. T. 



Descending to a tributary of Silver creek from that point, 

 several outcrops of massive sandrocks are seen, and we come 

 down to the base of the Catskill sandstones at 400' below 

 or 1395' A. T. At 1495' a very massive stratum of greenish 

 gray sandstone is seen forming a line of broken vertical 

 cliffs around the hills. 



Just north of Silver Lake a cliff sandstone is seen in the 

 summit of the hills 175' above the level of the lake, and 1825' 

 A. T. ; it is most probably the same stratum as that seen at 

 Maroney's. 



About one and a half miles south of Mud Lake, on the 

 land of Mr. M. Hill, a massive sandstone is seen outcropping 

 at 1480' A. T. and this is most probably the one which oc- 

 curs at Maroney's 100' above the base of the Catskill sand- 

 stone group. 



Just north of Quaker Lake and 150' above the level of the 

 same, another massive sandstone is seen at 1600' above tide. 



At the western line of this township, near J. O. Shay's 

 a massive sandrock is seen capping the hills at 1700', and 

 below it come 100' of red shale.
