river rock

Water-smoothed stone

River rock is stone that has been naturally smoothed and rounded by flowing water over time.

These rocks accumulate along riverbeds and shorelines, their edges worn down by constant tumbling.

In landscaping, river rock refers to this material sold for decorative use in gardens, pathways, and drainage: We lined the garden beds with river rock.
