Join a Discovery Center Naturalist for an engaging and informative hike on the Big River Trail. We will look for animal tracks and sign and discuss the physical and behavioral adaptations that enable wildlife to survive the harsh Northwoods winters. Please dress accordingly and bring your own snowshoes or use a pair of ours.  Space is limited; advance registration by 3/7 required.  Saturday, 1-3pm.  $10 ($7 members).
