Most often occupies open (not vegetated) although complex bottoms comprised of gravel to cobble-sized fragments of tufa and tufa stromatolites. This substrate is formed largely by calcareous material accreting through physical and biological precipitation of calcium salts as well as by transport of fragmented tufa from upstream that deposits to form armored bars where channels widen abruptly.
