Like some other bloggers I know, I can't resist pointing to yet another image from NASA's Earth Observatory site. This one if of Australia's Lake Eyre basin.
Just go read the description there. In how many places do we see a delta system and sand dunes cutting through one other?
And an amazing ecosystem to boot--see the Australian Broadcasting Corp. video (referenced by the EO site) here.
