Eastern Continental Divide points of Allegheny Mountain (Pennsylvania)


Allegheny Mountain is a stratigraphic ridge that extends northeast to southwest from south of Blue Knob (Pennsylvania)[specify] to a saddle point at the Savage Mountain anticline. It merges with Negro Mountain just north of the Cambria County line where the Berlin-Salisbury basin expires [1].




Eastern Continental Divide (ECD)

The ECD enters Allegheny Mountain south of Fraziers Pass and follows the Allegheny Backbone [2] southwest where it leaves the escarpment toward the saddle point to the southeast between headwaters of Flaugherty and Wills Creeks, at which the ECD enters the Savage Mountain anticline.[3]
