This was filmed in 2012, so doesn't include information about Iceland's Bardarbunga volcano, which has continuously been erupting since August 31, 2014 & "had already spewed out more sulfur dioxide than any other Icelandic volcano in the past several hundred years & showed no signs of stopping..." Just what we need, killer undetectable poisonous gas mists engulfing us as we unknowingly breathe it in.... http://www.newsweek.com/iceland-experiencing-its-biggest-co… :/
Wilpena Pound, near the Flinders Range National Park's southern entrance, is a geological curiosity. One of several oval basins atop mesas (flat-topped hills), Wilpena Pound is about 8km wide and 20km long. It appears to be a tiered amphitheatre of quartzite. The sole entrance is through a narrow gorge and across Sliding Rock.
