Replying to Video shooting in deep snow

So I just dropped this edit from our trip to grand targhe, where we were fortunate enough to have the deepest day of our life and our only true powder day of the year.

Anyways I struggled throughout the entire day keeping my lens clean as well as dealing with other things. So I am wondering what are your tips for shooting on snowy deep days if any? Thanks plus K
