I’ve seen plenty of fox tracks pretty much everywhere I’ve been skiing and snowshoeing but finding the maker of the tracks isn’t always so easy. And it’s usually a matter of the fox coming to me not me finding it. Since both skis and snowshoes make a lot of crunchy noise no matter how quiet I try to be, the wildlife usually know that I’m coming. When on skis or snowshoes I prefer to go light and only carry a 100-400mm lens as my longest since it’s a lighter, more mobile option. And, while I haven’t owned that lens long, it’s impressed me so far. But occasionally I’ll take the heavier gear and some times it pays off.
