That is so cool, fantastic detail. I hear yah on the cold fingers. Most the time I have to come in the house a few times because I just want to keep taking photos of snowflakes on the days that give big fat snowflakes or ice formations like this :)
I do agree Milanie sometimes I can't even press the shutter button because I can't feel my fingers. Your shot is excellent love those huge square crystals they remind me of diamonds....The weeds don't even look like weeds and the frost does a good job in transforming them to beauties....
