6. Western Plains (WP)
6.2 Sedimentary plains (Plains on unconsolidated (sedimentary) deposits
Along the coast near Port Campbell, the limestone plain has developed many karstic features, particularly sinkholes. Spectacular coastal cliffs, now eroded to give gorges, rock stacks and islands, and exposing cave entrances, formed by rising sea level over the past 15 000 years, mark the edge of the plain at the Southern Ocean. Associated soil types include deep sands over clay (sand depth may be variable). |
