I just love the background in this image. Perhaps the figure could have been a little closer so that we might see more of him.

I was wondering what causes these dark semi-circles across the Mer de Glace as I was looking down from the other side this summer. Does anybody know? Is it where water has run into the channel in the centre? Seems so uniform and unnatural looking.

Ah just Googled "Ogives". Apparently they're "Forbes Bands" caused by the seasons effecting the density of the ice. I did think they looked a little like the rings of a tree. Everyday is a school day!

Sorry to hog the comments, but does anyone know which seasons the light and dark bands are from? I guess the dark black ice is from the summers? The opposite of trees?

Yep, Google says it's deposited summer dust, with the troughs being from faster melting as it stretches over an ice fall in a previous summer. Fascinating!

They are indeed Forbes Bands - On the Mer de Glace specifically, they are caused by the periodical differences in snow cover and rock stability around the ice fall which vary the amount of entrained debris. Great photo BTW!
