Rock
River Rock is cobble- to boulder-size stone that has been rounded
by transport in a river or stream. The best river rock has some flat
surfaces and angles so that it stacks well, minimizing joint widths and
forming good corners. The parent rock type (sandstone, limestone,
granite, etc.) of which the river rock is composed, and the distance of
transport in the river, determine the quality of the river rock.
