21631 Mammoth Lakes Sunrise

We were at this 9700 foot location for shooting the panorama "41603 Moon set at Sunrise" (See the Panorama gallery). We were of course looking West watching the moon set and waiting for the Sun to rise behind us. When we looked back we saw this cloud dramatically lit by the rising Sun. The trees are dark (the Sun rays have not reached them yet) forming a wonderful silhouette.
