bare foot tree

I got a free bare root tree in the mail from The Arbor day foundation. Problem is I didn't get it until now. I live in Michigan and my ground is frozen. There is only a light dusting of snow in the grass but the ground is pretty solid. What do I do with the tree? What if I can't plant it tell spring? Can I put it in water? Should I container plant it tell spring? I also have no idea what kind of tree it is. I think it might be maple though.
