Mount Whaleback Western Australia

This is a picture of Mt Whaleback in Western Australia. This is about 0.5KM deep, 0.5KM across and 1Km in length. Now what I think is a bit crazy is the fact that this hole in the earth used to be a mountain!!!
This is is from the sky, http://www.hyvista.com/iom/iom_jan05.html
The picture I took is from 1995.
