26-Jun-2005 -- This visit involved a 9km (4 hour)round trip hike across the dunes from the Wapet Road (Kidson Track). We camped on the track the night before and started the walk to the Degree Confluence at daylight (the time on the GPS is South Australian time).
The 1:250,000 Auslig maps of this area show individual sand dunes. They are surprisingly accurate.
