Grizzly bears are some bad ass critters, no two ways about it. But pound for pound, the wolverine wins the One Tough Critter contest, hands down. And it’s not just because they’ll take on animals many times their size. For one thing, grizzly bears sleep most of the winter, while wolverines are out prowling around no matter how cold it gets. Heck, one guy was even monitored as he winter climbed straight up Mt. Cleveland in Glacier: he reached the top (5000 feet in 90 minutes!) and then just went down the other side. There was nothing he wanted up there; he just was climbing because that’s what tough critters do. Their jaws are so strong that they eat every part of a carcass, bones included. I’ve even seen video of a wolverine going up a tree after a black bear. They’re rare, and I thought that they were pretty much all in the Glacier Park area.
So I was surprised last weekend when the Montana Wilderness Association and Wild Things Unlimited offered a workshop to go out and learn about tracking wolverines and lynx just an hour outside of Helena. There are wolverines there? Cool.
We spent two hours on Friday night learning about winter tracking in general: information about stride, straddle, and direct registry that was nifty in itself. We (the citizen scientists!) were going to be looking for three animals in particular: lynx, wolverines, and fishers. On Saturday we broke into four groups and headed up four different drainages to search for tracks. Our group found interesting stuff right away: bobcat, coyote, snowshoe hare and deer tracks, and some unknown scat that our fearless leader collected.
We continued up the trail, trying hard to decipher the tracks we found in the crusty snow.
The big reward came when we discovered a fairly fresh elk carcass. Something had been eating on it recently, and had even buried it in the snow.
We started looking carefully, and found….wolverine tracks! They were not the best tracks, but they were clearly wolverine: large, with five toes, and with a gait and track pattern that is typical of wolverines. We may have even found lynx tracks, as well. There was even a bit of scat near the carcass (yay, poop!) My photos of the tracks are not the best, but I think you can make out the prints:
We had lunch near the carcass, and then headed back. When we all met up we discovered that three of our four groups had found wolverine tracks. One group even followed some tracks to a snowshoe hare kill. Amazing.
