im not exactly fond of the way the man is walking out of the photo, but overall i do like this photo. the mountains are very beautiful, not sure i like the boot prints in the snow. they seem to take away from the pristine nature of the scene
Although climbing is an action - I don't think that your depiction here fits the challenge.
Good shot though - nice rule of thirds - I like the way that the horizon leads you to the man in the distance.
