Tracks inscribed on snow by unseen animals offer tantalizing multilayered puzzles.
Football-sized bald-faced hornet nests, hanging from branches, are prominent in the winter landscape.
The reasons burls grow on trees are still not fully understood, but infection by viruses, fungus and bacteria are likely causes.
