Beach BI 37 lies in the northeastern corner of Lighthouse Bay. It is a crenulate 150 m long high tide cobble beach backed by slopes rising to 100 m with a 100 m high headland to the east and rocks extending 100 m offshore to the west. Three small creeks flow down the slopes to the beach. In between is an 80 m wide surf zone breaking over sand and rocks, with a strong rip against the eastern head. The main beach (BI 38) commences on the western side of the rocks and curves to the west, then southwest for 1 km, terminating at the north side of 100 m high Cape Bruny. Wave height averages over 1.5 m in the east, decreasing slowly to the west, with two to three rips dominating the eastern half of the beach, grading to a narrow low tide terrace in the west (Fig. 4.105). Some vegetated east-trending transgressive dunes have climbed part way up the eastern slopes behind both beaches. A vehicle track descends from the Cape Bruny ridge to the western end of the beach. read more
