LIBERTY. G 5 . 87 



The Chemung rod's come in about 100' below the base of 

 the 115' red shale and hence line the valley of Snake creek 

 at this point and the side hills for 200' up. 



Nos. 1-3 represent the lower half of the New Milford 

 sandstone group, and the members of No. 1 are quite mas- 

 sive, about 20' feet thick each, separated by shale. 



Just north from the top of this exposure, a great gap is 

 cut out of the dividing ridge between the waters of Rhiney 

 creek and a tributary of Snake creek. The cut-out extends 

 down 200' below the adjacent hills. 



No. 4 is the lowest exposed portion of the Catskill red 

 shale, and is almost blood red ; occasional layers of more 

 sandy material alternate with the shale. 



Passing west from the locality of the last section we come 

 to a long line of gray sandstone cliffs at 250' above No. 1, 

 or 1890' A. T. 



Near the western line of this township, is a small oval 

 body of water called Tripp lake; it covers about five acres 

 of ground, and has an average depth of 50' off the shore 

 line, though in the deepest portions it attains as much as 

 80'. The lake is surrounded by morainic debris and is 

 doubtless of glacial origin. 



At the forks of the road, on the Hanigan estate, one mile 

 northwest from Tripp lake, the outcrop of a massive sand- 

 stone is seen at 1500' above tide ; its place is in the New 

 Mil ford sandstone group.
