Sandfalls are found in sandstone canyons such as Antelope Canyon. A similar process occurs in submarine environments driven by water currents and gravity. Sandfalls on a large scale occur off the southern tip of the island of Mauritius, where strong ocean currents move sand from the high coastal shelf over the edge and into the abyssal depths. Sandfalls in the submarine San Lucas Canyon off Cabo San Lucas, Baja California were dived by Jacques Cousteau. Carter (1975) argues that the ubiquity of this process is evident from the examples from the sides of submarine canyons documented by Dill (1964) and from seamounts and deep-sea trenches documented by Heezen and Holhster (1971).Dill, Robert F.
