These dunes are obvious within the photograph below (The noticeable uplifted region is Mt Schank and the dunes span horizontally throughout the image).

We commonly know A different kind of sinkhole uncovered all around Mount Gambier as being a doline. Inspite of currently being smaller sized than craters, doline sinkholes hold their unique fascination.

"Some volcanoes that we take care of in eastern Victoria, there is a little bit of an alignment of a few of the volcanoes, and those while in the north are older than those while in the south," Dr van Otterloo stated.
