We got an early start, planning to do Mystery Canyon, shuttle sorted, permits sorted, gear sorted.
Had a nice walk to the head of the canyon, dithered a bit about where the trail down started, got going, scrambled amongst horrible chossy mess and scree, abseiled various bits, route not looking anything like the description and we got to an abseil that would mean the point of no return so we decided to scramble back up as we just weren't happy with the way things were. Back at the top we just had an 8 mile walk and over 2000 feet back to the valley floor in 38 C (100 F) heat - phew!
