Rocks uncovered by a drought and a lower level of the Potomac River on Olmsted Island 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.
