"Temperatures can rise to 50°C in summer and it has been known to rise to 60°C." The BOM would be interested in hearing this, given they think the all-time Oz record is 50.7 (
Oodnadatta, 1960)! The real numbers are scary enough, no need to exaggerate them! But seriously, this is an excellent trek write-up, makes me want to go there right now! Thanks in particular for the contact information for permits and verifying defence closures.
