unconsolidated intertidal material.

That portion of the shore between ordinary low and high water marks. Commonly used to describe any sandy area adjacent to a body of water.

Coast
seashore: the shore of a sea or ocean
a slope down which sleds may coast; "when it snowed they made a coast on the golf course"

slide: the act of moving smoothly along a surface while remaining in contact with it; "his slide didn't stop until the bottom of the hill"; "the children lined up for a coast down the snowy slope"
move effortlessly; by force of gravity
