Featured above is frozen forest observed the morning following a foggy night on Mount Loffa (3,445 ft or 1.050 m) in northern Italy. When the temperature dropped below freezing (32 F or 0 C), the fog droplets froze, forming a thick layer of rime ice upon everything exposed to the sky. Even at sub-freezing temperatures, fog droplets remain liquid until they alight on something solid to nucleate around; in wooded areas twigs and pine needles are typically targeted. See detail at upper left. Photo taken in January 2018.
