23. Clifford, in Susquehanna county. 



This large area, directly south from Herrick, occupies the 

 southeastern corner of Susquehanna. 



It is drained by Lackawanna river and the East Tunkhan- 

 nock, the latter carrying off much the larger portion of the 

 rainfall. 



The rocks of this township extend from near the base of 

 the Catskill sandstone series up through the Sub-carbonif- 

 erous into the Anthracite Coal Measures. Hence this is the 

 only township within the county or district that contains 

 any valuable beds of coal. The reason for it seems to be 

 this : The elevated anticlinal range of the Moosic highland 

 forks near the northeastern line of the township, the eastern 

 branch keeping on southward as the main Moosic range, 

 while the western branch extends southwestward through 

 the southern corner of Clifford as the Lackawannock mount- 

 ains ; the two arms of the anticlinal having thus separated 

 a canoe-shaped snyclinal comes in along what had previ- 

 ously been the crest of the anticlinal fold and dipping rap- 

 idly down to the south, catches the basal members of the 

 Coal measure rocks near the southeastern corner of Clifford.
