The North Fork South Branch Potomac River carves a deep valley through the heart of the Monongahela National Forest, defining the settlement patterns and travel corridors of this Pendleton County region in the late 1960s. The village of Onego and the community at Mouth of Seneca serve as focal points along the river valley, where life is shaped by the towering presence of Spruce Mountain and the distinctive ridgelines of Little Mountain.
