Rocks uncovered by a drought and a lower level of the Potamac River, at the Chesapeake and Ohio Canal National Historical Park, Maryland. The holes in the center rock are caused by circulating water holding a smaller rock or pebble up against the large rock, and the resulting friction eroding a "pothole," into the larger rock.
