Red Dust

The harbour bridge, obscure
As a city that is so concerned with itself as a spectacle, the current dustcloak that is choking Sydney must be doubly disorienting. There have been some amazing shots of the dust storms - the above is probably my favourite (taken, I assume from the Rocks end of the bridge) - but there are some other jaw-dropping efforts contained in these two Flickr galleries.
Edit: A fantastic piece on this from Dan Hill of City of Sound. (Cheers to John Coulthart for the tip on this).
