Marks Knob is a 6,169-foot mountain on remote Dashoga Ridge in the central Great Smoky Mountains of North Carolina, above the upper Raven Fork valley. The higher of Dashoga Ridge’s two peaks, it has twin summits, with the southern one as the true high point, and is covered in dense Southern Appalachian spruce-fir forest over Precambrian metamorphic sandstone. Because it lies entirely within North Carolina and not on a boundary line, it drew less early notice than many major Smokies peaks. Former logging-era trails once crossed it, but their abandonment left a difficult, overgrown approach that made Marks Knob a secluded and demanding destination for hikers.
