Description
Spectacular sea cliffs in this area are formed of red Silurian Tumblagooda sandstone. At Shell House Cove this unit is overlain unconformably by the type section of Triassic Wittecarra sandstone (8m) and Kockatea shale. The upper part of the cliffs is white, formed of Pleistocene Tamala limestone, unconformably resting on the older rocks. Sedimentary structures at Red Bluff, at the north end of the site, include a widespread pebble marker horizon and the enigmatic fossil tubes known as Skolithos, probably formed by a soft bodied worm like animal, in a similar fashion to present day polychaete worms. There is therefore considerable geological interest, attractive colour and impressive coastal scenery in the area, which forms part of the Kalbarri National Park.
