We had “ice fog” this week in Edmonton, a fog that arises when it is so cold the humidity in the air freezes and the world is dressed in shadow. Amazing. Ice crystals dancing in the air:

” When a prairie winter hits its stride, the vapour in the air freezes and the empty spaces between all things sparkle and shimmer as the wan light passes through. Infinitesimal prisms of frozen humidity separate the light that seems suspended now in what one thought was a void.” (from Ivan the Giant)
