old can, Terrapinna Gorge

I saw this old, rusty  can lying amongst rocks in the walls of the Terrapinna Gorge in the Northern Flinders Ranges:

I was on a camel trek in the Northern Flinders Ranges  from Blinman to Mt Hopeless. I spent the best part of a day wandering through the gorge and around the Terrapinna Tors circuit above the gorge. My understanding is that the Hamilton Creek flows into the gorge.
