I think it's a co-incidence, for me it shows snow capped mountains, and I'm in San Francisco. We don't have mountains, or snow anywhere short of driving a few hours.
In Seattle it shows a snow-capped volcano (Mount Rainier), an illustrated version of the Space Needle, the Pike Place Market sign, and a couple downtown buildings from the viewpoint of Kerry Park[1]. They have a generic rotation of images plus some location-specific ones. I'd love to see the whole collection laid out somewhere.
