Water-caused Erosion in River Rocks
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.

Geologist collects ash downwind of Halema‘uma‘u, Kīlauea
Ash and other lava fragments erupted from the new vent in HALE‘Ama‘uMAU Crater were collected almost daily from several wooden "tear catchers" located near the crater rim and from many more plastic buckets nearby. Six years later, ash collections are still made several times a week.
