HERRICK. G 5 . 137 



On the South knob, at an elevation of 2400', is a wide 

 level projecting ledge of rock formed by a cliff of the Mount 

 Pleasant conglomerate. From this point one of the grand- 

 est pamoramas to be seen in the State bursts upon the eye, 

 and the locality has long been known as Prospect Rock. 



From this elevated summit the eye takes in at one sweep, 

 the valley of East Tunkhannock 1200' below, Crystal Lake, 

 set like a jewel among the hills, the curling smoke from 

 the hundreds of mines along the Lackawanna, as far south 

 as Scranton, while beyond this still, in a long line of billowy 

 crests, rise the blue outlines of the Moosic mountain range. 

 A carriage road extends to within a short distance of the 

 "view" and it is frequently visited by pleasure parties. 



The rocks of the township belong entirely to the Catskill 

 series, with the exception of the gray sandstones capping 

 the North and South knobs of Elk mountain which should 

 most probably be included in the Sub -carboniferous. 



The following succession is seen in descending from the 

 summit of North knob past Mr. Burdicks : (Fig. 38. )

This long section is obtained in traversing an air line dis- 

 tance of only two miles. There is every probability that 

 when the broad valley of East Tunkhannock was buried 

 under the ice the elevated peaks of North and South Knobs 

 rose above the Mer de Glace like islands. There are no
