River rock, also known as river stone, is a type of natural stone that is typically found in river beds, streams, and other waterways. It is a rounded, smooth stone that has been shaped and polished by the natural movement of water over time.
River rock is often used for decorative purposes in landscaping and outdoor projects, thanks to its natural beauty and durability. It comes in a variety of sizes and colors, ranging from small pebbles to large boulders, and can be used in a variety of applications.
