Doghouse Hill headland and landslide complex. A high, steep cliff composed of Liassic sandstones and marls fails mainly by rockfalls. Sediments released accumulate on the foreshore forming boulder aprons that cut the eastern extremity of Seatown beach and block drift. Pockets of gravel remain amongst the boulder aprons suggesting that a continuous beach formerly extended around the headland prior to suffering depletion in the 19th and 20th centuries. Some renewed landsliding is evident in 2001 indicating that a long period of marine erosion would be required before a beach could become re-established along the cliff toe.
