|Location:||285935. Opposite Deauville Street, Beaumaris.|
Beach Road, Beaumaris. The significant features may be viewed from the cliff top.
Crown land, City of Mordialloc.
The site displays the dip of the Black Rock Sandstone (averaging 15 to 20 degrees) where the beds are warped along the Beaumaris Monocline. The monoclinal warp is best seen in profile where there is a small cove and sea cave opposite Wells Road. The contact with the Red Bluff sands is seen here in the upper part of the cliff. Small reefs lying parallel to the coast are resistant sandstone beds outcropping along the strike of the monocline. Towards Charman Road, the dip steepens to 25 degrees and the strike becomes more northerly as the monocline trends inland. East of Charman Road, the softer Red Bluff Sand is warped down to sea level and the erosion of this softer material has produced the pronounced bight and simple curving coastline between Beaumaris and Mordialloc.
Marine invertebrate fossils occur in the Black Rock Sandstone although not in as readily available numbers as the outer Beaumaris sites (Sites 59 & 60).
Regional. The site is a very clear example of a monocline fold. The variation of dip and strike of the beds is clearly displayed, as is the effect of the changing lithology (from Black Rock Sandstone to Red Bluff Sand) on coastal cliff profiles. The site also has significance as a fossil locality.
Class 2. The cliffs should not be further vegetated or stabilized. The parallel reefs are an important part of this site and should not be interfered with. Viewpoints from the cliff top path should be positioned to allow a clear profile of the dipping beds of the monocline as they occur in the cliffs and near shore reefs.
