Mt. Race, Massachusetts. All of these shots were taken in a single puddle on the Appalachian Trail on the north ridge of Mt. Race. I don't know enough about ice crystals to understand why some puddles produce crystals and others don't but when I find a patch of great crystals like this it's like finding gold. The only downside is that the gloves come off and one's hands can get cold in a long session. The day I took these was relatively mild so hands didn't suffer and as a result, more ice shots.
