Cloud Iridescence

Cloudwatching in the mountains offers an endless variety of cloud formations, partly because of how mountains shape air movement. On this morning, we saw developing lenticular clouds followed by a spectacular display of iridescence. Diffraction—light bending around the droplets—scatters light waves into a shifting palette of often pastel, but sometimes very vivid colors.
