"To muse, to creep, to halt at will, to gaze ... such sweet wayfaring" William Wordsworth
What is that? It looks like a concrete truck? But why? I have been to Coober Pedy, and THAT was unusual!
According to the Lightning Ridge info site "Opal dirt' – sandstone and clay mined from the opal level – is taken up to ground level using a hoist or blower, and dumped into the back of a truck.The opal dirt is then washed down by tumbling it for several hours inside a modified cement mixer called an agitator. Finally, the remaining 'tailings' are sorted, with keen eyes searching for any hint or trace of opal colour."Yeh. I have been to Coober Pedy and Andamooka both very unusual.
Hope you find a big opal. I'm going to Coober Pedy next year, my first opal town.
We were seeking warmth and new places, not opals. You will enjoy Coober Pedy.
