Profiles of Rivers and Mountains. 



Fig. i. Profile from Charleston, W. Va., up the Kanawha, New and 

 Greenbrier Rivers, to the Divide, and thence down the Jackson and North 

 Rivers to Lynchburg, Va., on James River. Also the profile of the upper 

 Roanoke is given and its location with reference to New River, and the old 

 abandoned valley connecting the two. The upper parts of New River are only 

 roughly sketched.

 apart.

Fig. 2. Profile along the crest of the Allegheny Front, and the ranges 

 farther south (Peters and East River Mountains), which form its continua- 

 tion. The rivers and creeks at the eastern foot of the mountains are indicated 

 by dotted lines. In the region of the B. & O. Tunnel exact data are missing. 

 The two sections of the profile are connected at x — y. The range behind 

 Dans Mountain is Savage and Backbone Mountain.
