Squirrel Footprints on Our Doorstep!

This morning we woke up to a fresh blanket of snow, the first (real) snow of the year for us!  Naturally this means that I must do all of my first snow traditions, including watching the Battle of Hoth scene from Star Wars Episode V: The Empire Strikes Back, and wearing my Mammoth and Mastodon Madness t-shirt from the Denver Museum of Nature and Science.  Anyways, on my way over to school, I saw a few footprints.  I took a few pictures on my phone so they aren't very good looking, but I believe them to be from the eastern fox squirrel, the type of squirrel that is just so common around here in Boulder, Colorado!  If anyone knows otherwise please let me know, but I am 99.99% sure that this is what we are looking at!  The first two pictures are the ones that I took with my phone.  The first picture has an impression of my right index finger in the snow next to the footprints for scale.  The third picture is a picture that someone else took of some eastern fox squirrel footprints in the snow too!
