The Bitterroot Valley has lots of animals wandering around the forests. One of those critters is the porcupine. If you know what you're looking for, you can see the little animal's tracks in the snow during the winter.

Of course, they are visible during the day at times, too. In this week's Metcalf Wilderness Journal, Bob Danley of the Lee Metcalf National Wildlife Refuge spends some time talking about the prickly guys. As you can see in the photo, they are sometimes seen in trees, blending into the branch. Bob's report talks about the long lifespan of porcupines and other facts. We have Bob's observations every Thursday on KLYQ 1240 AM during the "Bitterroot Morning" newscast at about 7:45 a.m. We also have some of his previous shows on our YouTube video channel.
