The line of three in the foreground on one picture suggests that they are lying along faults/ clevage/ bedding in the rock which probably means they are caused by natural erosion. But you never know!

If you get a conglomerate with pebbles on a bedding line and they fall out you get a common misapprehension of "cups " .
