Distinctive feature of this profile line is the pebble foreshore. The bluff is actually a vegetated dune. Deposits of heavy minerals are common. The bluff was stable during October 1973 to December 1974, though the beach was active particularly in late 1973. Between October and November, cubic meters per meter eroded. This was followed
