CLINTON. G 5 . 177 



The dip is quite strong (8° — 10°) in a western direction or 

 toward Forest City ; so that some of the preceding intervals 

 are the result of close estimation. 



The Griswold's Gap conglomerate was named from this lo- 

 cality ; it is a very hard, coarse whitish stratum, containing 

 vast quantities of snow white quartz in large angular and 

 generally flattened pebbles uniformly distributed through 

 the mass of sand. I regard it as certainly a member of the 

 Pocono series ; elevation of base 1975' A. T. where first seen 

 at the summit of Griswold's Gap. 



Nos. 3, 5, and 7 are all massive, hard, gray, much current- 

 bedded sandstones, and very much resemble the rocks that 

 are seen in the summits of Ararat and North knob at the 

 same horizon. 



I have identified the Mount Pleasant conglomerate here 

 not without some misgivings, but still there are more rea- 

 sons for than against it, because if this be not the 3ft. Pleas- 

 ant conglomerate then No. 1 must be that stratum ; but the 

 latter has the same elevation here as the conglomerate at Mt. 

 Pleasant, 7 miles due north, and in that distance there ought 

 to be a rise of 300' in the rocks which would just bring No. 

 9 (1700') up to the elvation (2000') of the Mt. Pleasant stratum. 



Then another point in favor of its identity with the Mt. 

 Pleasant conglomerate is the fact that it contains a stratum 

 near its base filled with reddish-colored quartz pebbles, a 

 feature often seen in the former rock ; it does not appear 

 quite so massive here as usual ; but its complete exposure to 

 atmospheric influences in the vertical cliff has doubtless con- 

 tributed somewhat to break it up, and render it less massive 

 looking. 



As we go still further east from this point, the rocks con- 

 tinue to rise quite rapidly in that direction for about one 

 mile, when the dip begins to flatten very fast, and then the 

 locks soon become almost horrizontal. 



About one and a half miles east from Griswold's Gap, a 

 massive grayish-white sandstone, with a few pebbles, is seen 

 at 1435', still dipping northwestward, and this is most prob- 

 ably the representative of the Cherry Ridge conglomerate. 



From the summit of Griswold's Gap a small stream starts
