Without any visibility to navigate, I navigated the above water crossing by the sound of the water running over rocks. Hike towards louder water because the water is more shallow and likely to include rocks to cross with. Keep a straight line for a quick crossing, not a perfect crossing. And dive right into it — there is no time to be shy about crashing through the reeds, vines, mud, or bush here.
