The patterns and colors in the Zagros Mountains of Iran are interesting enough. For example, the infrared view provides a patina-like outline to the mountains. But something more happened to this unique landscape. Interrupting the mountain patterns are irregular dark patches called salt glaciers. What began as salt domes buried under the rock pushed up through the Earth, squeezing to the surface like toothpaste.
