Bring a 30 cm x 30 cm square of sleeping mat foam. (The blue stuff) It is great for kneeling down in the snow and keeping you dry. It is also good to sit on when you are warming up with a cup of hot tea.
I have a similar pad that is part of the padding I constructed for my camera pack. Great for snow! Also for long sits on rock, damp ground, etc!. Also for setting equipment on.
