Iceland: first impressions

I arrived in Iceland yesterday.  Having read a number of novels set in the country I had a certain idea of what the landscape and Reykjavik would be like, but oddly it has quite a different feel.  On the drive from the airport to the city there were only four colours on display: light and dark grey, muddy green and fawny green.  And there were no trees.  At all.  And the city is low density, sprawling and modern.  I usually praise novels set in Iceland for their sense of place, but now I'm not quite so sure.  Nevertheless, I'm quite taken by the landscape and it's bleakness and scale.
