Hoar Frost

What's that you say? Hoar Frost is created when solid surfaces are cooled to below the dew point of the adjacent air. It makes amazing looking crystals on everything from the tree branches to the christmas lights still hanging on our house (because it is too cold to take them down). The crystals look like spikes on a porcupine. Soo cool! Later in the day when the temperature changes, the crystals get blown off the trees and it looks like it is snowing all over again! Ahhh, Minnesota! Here are a few photos from my walk around the loop on this foggy and frosty day. January 13, 2010.
