[Rockhounds] Australia’s subterranean oasis

[Kreigh Tomaszewski]

Nothing about the Australian town of Coober Pedy is for the faint of heart
– it’s blisteringly hot, located in the country’s remote Outback interior
and is usually covered in a thin veil of red dust from local opal mines.
But rather than move to a cooler, more hospitable climate, residents have
gotten creative, building a subterranean community in old mines and
creating everything from dug-out homes to churches. Today, around 60% of
Coober Pedy’s 3,500 locals live underground.
