Abstract
FLUTE marks abound as moulds in rocks attributed to turbidity current action1 and are not uncommon in beds assigned a fluviatile origin2. It was early recognized that flute marks are caused by the eroding action of currents of water on cohesive mud beds. Much later it was found experimentally1 that the growth of flutes depended in some way on eddying motions in the current of fluid acting on the bed, although no clear idea emerged at the time as to the physical character of these eddies nor as to how they were involved in the bed erosion.
