The cold bright sun causes changes in the snow and ice. As the light and temperature changes, there are more photographic opportunities to capture Mother Nature’s art.
I love the interplay of the shadows and the sparkle of the snow as this wave is seemingly frozen in time.

Beautiful. You need to publish a book, Barbra. Your photos of nature are captivating.
I love the frozen dynamics of that frozen wave! Reminds me a little bit to a related phenomena I pictured some years ago in the Swiss mountains: http://dl.dropbox.com/u/18307653/Roulade.jpg
Cheers and have a nice time!
