Fortescue Bay is a remote 4 km deep bedrock embayment located to the lee of 134 m high Cape Hauy. The bay has a 1 km wide entrance widening into the northern small Canoe Bay, a popular anchorage, and the larger main Fortescue Bay. Beach T 309 is located at the southwestern base of the main bay. The entire bay shore is surrounded by steep, densely wooded slopes rising 100-200 m and all are part of the Fortescue Forest Reserve (Fig. 4.56). The 12 km long Fortescue Road winds in from the highway to the southern end of the beach, where there are camping and boat launching facilities. The beach is 700 m long and faces northeast towards the bay entrance. Lower refracted waves reach the shore averaging about 0.5 m, where they maintain a lower gradient reflective to low tide terrace beach. The beach and low backing foredune form a barrier across the mouth of Agnes Creek, which is impounded behind the centre of the beach as the small Fortescue Lagoon. The lagoon occasionally breaks out across the beach, causing a slight protrusion in the centre of the beach, with some rocks deposited on the seafloor off the mouth. read more
