This is really cool -- it plays with one's perception of scale in a big way! The glacier looks like a small country road with tire tracks, and that's what I thought it was ... until I realised that those were mountains alongside it. What's most amazing to me is how neither element (the glacier nor the mountains) seem to harmonise with each other, which creates a really strange and fascinating effect. It's like they're elements from two entirely separate photos -- an astonishing optical illusion. Terrific photo.
