Allegheny Mountain is a stratigraphic ridge that extends northeast to southwest from south of Blue Knob 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.[4]

The Eastern Continental Divide enters Allegheny Mountain south of Fraziers Pass and follows the Allegheny Backbone[5] 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.[4]: 9
