This image is a close-up shot of ice that formed on a supraglacial stream on the Llewelyn Glacier in British Columbia. The shot was taken in the morning, after it crystallized the night before. As the night began, a little ice formed at the edged of the stream. Then the level of the stream went down (because sun-induced meltwater feeds the stream) and a little more ice froze. Continued iterations covered over the entire channel with these little stairsteps descending from both banks and meeting in the middle. The image is about life size with a screen resolution of 72 dpi (that's the standard).
