Lackawanna river, which flows south along the eastern 

 line of Susquehanna county (draining the western slope of 

 the Moosic mountains) cuts straight through the Lack- 

 awannock range at the southeastern corner of Susquehanna 

 county and, entering the Lackawanna coal basin, flows down 

 its trough southwest to the Susquehanna river at Pittston. 

 The slope of this valley has already been given under the 

 head of R. R. levels. 



Tunkhannock creek with its numerous tributaries comes 

 next west from the Lackawanna river, and drains a large 

 area from the southern slope of the east and west divide, 

 south west ward, into the Susquehanna river at Tunkhan- 

 nock, in Wyoming county. The main tributaries of this 

 stream are the Bast Branch, emptying into it near the 

 southern line of the county, and Martinis creek which 

 flows southward from the great gap in the east and west 

 divide near New Milford, emptying into Tunkhannock two 

 miles south from the county line at Nicholson. 



The descent of this stream is shown by the following bar-

Meslioppen creek and its tributaries, Little Meshoppen,

 southern slope of this divide. 



Tuscorora creek, which empties into the Susquehanna 

 near Laceyville, drains the extreme southwest corner of 

 the county. 



Wyalusing creek rises on the elevated plateau near Mont- 

 rose, and flowing westward with a rapid fall drains with its 

 tributaries (the North and Middle Branches) a large area 

 out of the central western portion of Susquehanna Co.
