Pliocene – Pleistocene – Holocene and Modern Dune Systems of South Australia

What are we exploring?
Pliocene – Pleistocene – Holocene and Modern Dune Systems of South Australia

When?
Sat  9 July to Mon 11 July 2016

Where?

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.

Cost

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.hesp@flinders.edu.au>).

 

Payment and registration

If you wish to participate you need to register and pay onlineAs a backup, please email me a copy of your registration also.

YOU MUST REGISTER BY THE 30TH MAY LATEST.  Please note that if less than 20 persons register for the trip, the price will have to increase due to the fixed price of the bus hire. If less than ~12 persons register the trip may be cancelled. In this case you will receive a refund.

What to bring / wear

Warm clothing (mean temp range for July is 80 to 150), raincoat (this is the rainy month – mean rainfall 104mm), hat, sunscreen, water bottle, joggers/tennis/shoes/light boots, small daypack, camera.
Accomodation in Adelaide (11 June, 2016)
Unless you have a late flight out of Adelaide on the 11th, I recommend you stay at Glenelg which is a very nice beach suburb in Adelaide, 20 min from the airport and 20-30 min from downtown. There are many cafes, pubs and restaurants at this location and a great beach promenade. Two reasonable hotels on the beach front are The Oaks Plaza Pier (~$126/night) or the Stamford Grand Adelaide Hotel (~$131/night). You can take a tram/street car from here into town and back also.

If you plan to stay longer I can email you some recommendations but there is lots to see and do; take a look at doing a wine tour of the nearby McLaren Vale or Barossa wineries (fabulous reds), Kangaroo Island, hire a car and drive through the Vale and onto Victor Harbour and surrounds, or head downtown to the café/bar districts, shopping and/or museums.
