Question:
Silver Mountain Water has a hint of snow in the dry down.
Geir Ness has a spring air with snow on the ground accord.
Himalaya is a great frag, but I don't get any snow or winter from it (other than it's name).

Answer:
I find there's a really cold, shivery feel to Apres l'Ondee, and I love to wear it when it's snowing (as it is today, here; pish to all this first day of spring nonsense we're meant to be having tomorrow).

Answer:
I will second L'eau d'Hiver not only because it smells like fresh snow covered flowers drizzled with honey, but because it also smells like pure, untainted heaven.
I also heard that "snow" by Demeter smells like it... somewhat. I'll have to check it out though...
