Quick Summary

Ice fog is a type of fog composed of ice particles. It forms in extremely cold temperatures when the water droplets that make up fog freeze into ice crystals. The visibility in ice fog can be significantly worse than in water fog with the same concentration of condensed water. This phenomenon is also referred to as pogonip in the western United States, where it forms in deep mountain valleys during winter as tiny, biting ice particles.1234
