Category:Needle ice
Français : Les pipkrakes ou aiguilles de glace sont des cristaux de glace, longs de quelques millimètres à quelques centimètres, qui se développent perpendiculairement à la surface du sol quand la température de l'air est négative. On les trouve surtout dans des environnements périglaciaires humides.
