while on this topic i have recently become fascinated by the Lake Acraman asteroid/comet!? impact site in SA, in Gawler Ranges. one of the biggest in the world (~90klm)
Its on my places to go one day now, along with wolfe creek, and Gosses Bluff craters. wouldnt it be cool to do some imaging from these sites
