Before we got to Antarctica my intuitive feel about the landscape was a lack of colour, Edward Weston and Ansel Adams territory. It isn't like that at all. Black, red (jasper, I think) and brown rock and mountains. Ice colours, particularly with the sun behind, are stunning. Blues from old ice that has been compressed, greens from algae reflecting up. And icebergs erode from underneath and then capsize and continue the cycle. Hence the varied size, colours and textures.

There's a pile of fossils that makes some good points about the way that Antartica is viewed. Don't take them home, just find another (not hard, just bash open a few likely looking rocks and you'll probably find a fairly old fern) and add it to the pile. Let's hope it stays that way. But, of course, the counter argument is maybe that there have never been any free and democratic elections there. So that's a risk.
