Marshmallow-like Formations on Cannonball River at Regent, ND
Marshmallow-like formations were photographed on the Cannonball River at Regent, North Dakota (USGS streamgage 06350000) on April 3, 2018. Foam is produced naturally from organic material in the water in combination with turbulence resulting from water flowing over the weir.

Ice Jam on White River near White River, SD (06447450)
Ice jam on the White River near White River, SD (USGS streamgage 06447450) on March 15, 2018. Ice jams occur when floating ice carried with a stream’s current accumulate at any obstruction to the stream flow. These ice jams can develop near river bends, mouths of tributaries, areas of decreased river slope, and upstream of obstructions like bridges.
