One of the best things about having snow on the ground is how animal tracks are suddenly visible. Here are some photos I took of animal tracks on my last hiking trip to New Hampshire.
Red squirrel, judging by the length of the stride.
I had seen some interesting ruffed grouse tracks on the way up the mountain, but by the time we descended, human tracks had obliterated them. I should have phtographed them on the way up, but I was intent on reaching my destination. Lesson learned.
