The term "river rock" refers to a diverse group of rocks that have been worn and rounded by the action of moving water. Inshore banks of shingle (large quantities of pebbles) exist in some locations, such as the entrance to the River Ore, England, where the moving banks of shingle give notable navigational challenges. Cobbles offer a beautifully natural way to transform any garden, providing a riverbed, beach or cobbled look to any outdoor area.
