A rainbow cloud

This was quite a spectacular cloud formation, seen over Ptarmigan Cirque in Kananaskis country yesterday. Though this particular photo doesn't do justice to the scenery, I wanted to capture the cloud (and without any people in the shot). It is one of my favourite places, though I have only ever been there maybe four or five times ever. I will be posting further photos over the next few days that give a much better idea of the magnificent scenery, diiferent in each direction. Thanks, Robin and Cedric, for this absolutely perfect day out in the mountains!
