What are we exploring?
Pliocene – Pleistocene – Holocene and Modern Dune Systems of South Australia
Sat 9 July to Mon 11 July 2016
The field trip will take 3 days beginning at Mildura at 9am Saturday the 9th July and ending on the late afternoon/early evening of 11th July in Adelaide. It will cross the most extensive uplifted Pliocene-Pleistocene multiple barriers system in the world, traversing both coastal and aeolian desert dune complexes including lakes and lunettes, and also a variety of Holocene and modern coastal dune systems (foredune and foredune plains, blowouts, parabolics, clifftop dunes, and transgressive dunefields) including one of the three longest beaches in Australia, and classic aeolian calcarenite (and dunerock) coast. The trip will also enable you to see some iconic Aussie animals in the wild/semi-wild, experience the mallee culture and environment, examine living stromatolites and Holocene volcanoes, and visit a couple of fabulous wineries. The details and highlights of the trip are outlined below.
The cost is $440 Australian (~ USA$335.00 on May 2nd) which includes bus travel, accommodation and the first day’s lunch.
The cost of day 1 dinner, day 2 breakfast, lunch and dinner and day 3 breakfast and lunch costs are separate (i.e. additional, and not included in the $440). Please note that in order to keep costs down, accommodation will be shared rooms. If you have a partner of preference please let Patrick know as soon as possible (email: <Patrick.email@example.com>).

Mt Gambier to Robe (through Millicent, Tantanoola caves and ancient seashore/cliffs) along Pleistocene barrier systems. Stay at Robe.
DAY 3:11th July
Breakfast at Robe (at your cost). Collect lunches.
Visit Pleistocene aeolian calcarenite cliffs exhibiting multiple low sea level dune and palaeosol sequences, plus stacks and rock platforms.
Robe to Lake Fellmongery and modern stromatalites. Then to mid Guichen Bay Holocene foredune plain examining relict foredune plain, prograded barrier, and modern foredune and beach. Then cross the penultimate interglacial barrier to Toops road, the southern end of the Younghusband Penninsula/Coorong lagoon system to examine ultra fine carbonate very low energy beaches and dunes. Then to The Granites to examine the Holocene paleo-lagoon system, foredune plain, modern dunes), then to the last Interglacial relict foredune plain prograded barrier; then to 42 Mile Crossing to visit high energy beach, Holocene and modern transgressive dunefields, parabolic dunes, foredunes and blowouts (NOTE: this portion has a 3km walk through dunes). Then to Adelaide crossing the Murray River and Mt Lofty Ranges. Drop-off at Glenelg.
