Stonetool Sandblow


      Sandblows develop over thousands of years. Strong onshore winds erode and transport sand. Weak points in the shoreline dunes develop into "blow-outs". Sand blown inland from the coast spreads grain by grain, engulfing vegetation in its path.   

      There is a constant battle, a tug of war between sand and plant life. The apex of the invading body of sand advances inland while "arms" of loose sand trail behind. Gradually these margins may be recolonised and stabilised by plants.

      The area takes its name from aboriginal artefacts found in the area. 

      It rises 125m above sealevel and stretches more than 2km inland and it advances up to one metre every year. New sandblows may develop when stabalising plant cover is damaged by fire, vehicles or pedestrian traffic.

      We couldn't access the area but perhaps one day with an escorted guide I would love to be able to photograph this area from the "inside"!
