THE mountain region of North Carolina is not a unit, dominated by a single range or group of mountains, but is a complex containing several features of nearly equal topographic importance. These are (i) the Blue Ridge, (2) the eastern Monadnocks and Piedmont valleys, (3) the Unaka Range, (4) the central moLuntain groups and intermontane valleys.' Tue Blue Ridge.-The Blue Ridge may be regarded as forming the extreme eastern range of the Appalachian Mountains, carrying the main divide between the

Three other peaks reach above 5,OOOft (i,525m), and a dozen or more, most of them in North Carolina, are above 4,000ft (,220m). The most striking topographic feature of the Blue Ridge is the great difference in slopes on its opposite sides, for it is steep on the eastern and gradual on the western slopes. The eastward-flowing streams have cut back into the mountain belt, and, having the advantage of a more direct course to the sea, have encroached upon the territory of the westward-flowing streams, and have robbed them of portions of their drainage basins.
