What you’ll learn

  1. Wind Draws the DesertExplain how prevailing winds, linear dunes, geology, and fire scars create visible patterns in the Great Sandy Desert.Dune height and spacing reveal wind; contrasting surfaces and burn scars reveal that the desert is more than one field of sand.
  2. Water Leaves a RecordDistinguish ancient drainage traces from ephemeral salt lakes and read what satellite colors reveal about water and land.Lake Auld preserves a Paleocene river system, while Lake Hazlett, Lake Willis, and Lake Mackay show water’s brief modern return.
  3. Country Holds Human HistoryPlace the Canning Stock Route within the living homelands and knowledge of the Western Desert peoples it crossed.Wells and tracks are later marks on Country whose waters, paths, and stories were already known and used.

Questions this course answers

What makes the long dune lines so useful for reading the desert from space?

NASA describes the linear dunes as aligned with the prevailing winds, which typically blow from east to west.

What does Lake Auld preserve?

NASA identifies Lake Auld as part of a river system probably active in the Paleocene, more than 55 million years ago.

What is missing from a map that shows only the Canning Stock Route’s wells?

The National Museum of Australia describes the route as crossing the lands of groups including the Martu, Wangkajungka, and Walmajarri, whose homelands predated the survey.
