Middle Bluff - WA

Yamatji Malgana Aboriginal Country

Middle Bluff forms the northern end of the larger embayment and the southern boundary of a 10 km long lagoonal system connected by a 200 m wide tidal inlet. The beach commences at the bluff and trends to the northeast as a 1.3 km long series of multiple overlapping recurved spits, with salt flats, and then mangroves occupying the inter-ridge depressions. The nature, shape and length of the beach vary as new spits move slowly along the beach adding sand to the northern embayment, which has sand and tidal deposits extending 3 km offshore. The end of the spit reaches across the sand flats to the deeper tidal channel. In addition to the spit, there has been some dune transgression across the rear of the 300 m wide point, now indicated by vegetated walls of former parabolics.
