SUPERIOR, Wis. — Finding a bear den randomly in the woods is tough, even if you know what you are looking for.
Bears use a hodgepodge of different shelters for dens — everything from the space under uprooted trees and hollows in the ground to piles of sticks or a few downed trees and even culverts.
When it's time for bears to take their winter naps, usually by late October or early November, they don't seem to be very picky where they set up shop. And once they're in the den they don't often come out to be seen or leave tracks in the snow.
