Inland Dunes

Qpd

The inland sand hills and dunes cover many of the terraces between Qp2 to Qp5. They form a discontinuous mantle over the alluvial plains east of Blackall Creek, and become more extensive east of Perry River. The dunes in these areas were most likely formed from sands blown from these streams by the prevailing westerly winds, particularly during periods of aridity associated with past glacial periods.
