11-Oct-2012 -- Continued from 23S 130E.

Having reached our first CP at 23S 130E with relative ease, we were all fired up to reach 24S 129E about 18 km to the east of the Sandy Blight Junction Track. Because of thick vegetation, we were unable to get the vehicles more than a few hundred metres off the track, and a 36 km walk in 40 degree heat seemed imprudent.

Instead we spent two days exploring the Mu Hills and the Sir Fredrick Range. Keen to make amends we decided that 26S 128E looked achievable. This confluence looked like low hanging fruit, and indeed it was. We had several GPS units with us - an old Magellan Sportrak Color, several small no name units from China loaded with OziExplorer, a brace of iPhones, an iPad, and a Nexus 7. With every unit displaying 'zeros' we felt confident of our position to less than a metre.

The confluence is located about a kilometre south of the main road between the aboriginal communities of Blackstone and Jamieson. To the east lie the Blackstone Hills. Here lies a place called Singing Rock where the stones possess a musical resonance when struck. Walking up into the gorge reveals ancient ochre rock paintings. At the head of the gorge a spring flows for much of the year. Our trip was to take us east to Wingellina, then through the north west corner of South Australia, then onto Kata Tjuta and Uluru.

Continued at 25S 131E.
