Typical NC stream, fresh off the Piedmont, meandering through Triassic basin sediments. These finer sediments build good point bars, and will hold a slope; geomorphologic indicators for bankfull, are not hard to find. Relatively recent erosion is undercutting veg on the outside of the meanderbend. The point bar is under-sized for the depth of the undercut, meaning that this is a gully. The fine substrate can support tighter bends then if the substrate were sand.
