North Cascades Highway is nearly open. The snowmobiles are put away, the traps are closed for the season and the wolverine crew has moved on to other endeavors. A few camera stations wait to be collected—hopefully holding a few late-season wolverine pictures on the memory cards. Yet there is one last aspect of the 2010 season that we all wait on.

Somewhere on a shelf in the office are vials with dates and GPS coordinates carefully recorded. Inside is blue desiccant and wolverine hair. In a drying box outside the office door is a collection of wolverine scat. This is the culmination of yet another aspect of the wolverine study in the North Cascades—following wolverine tracks to collect hair and scat.

To this end, members of the crew took several trips into the backcountry in search of the elusive wolverine. Multi-night trips. Backcountry skis and sunblock. Other people do this sort of thing for fun, but this was for science. Someone had to do it, right? In our defense, it is a bit of work. Heavy packs and cold nights. And a lot of GPS work. Everything had to be recorded—the exact route followed, any tracks encountered, and a plethora of details of weather and snow conditions. Not your usual backcountry trip in search of slopes of deep powder. A scientific expedition in search of wolverine tracks. But hopefully a few good turns in the process.

You would think it wouldn’t work.

First of all, the wolverine is an elusive creature. It inhabits the untrammeled heights of mountain ranges and is rarely seen or documented. So far this season, with ten traps open every day, we’ve captured just one wolverine. We’ve seen few tracks. But still, this winter we’re trying something new—getting photographs of the chests of wolverines. It is an idea only recently pioneered by Audrey Magoun, a wolverine researcher in southeast Alaska. And it is a brilliant idea.

Wolverines, it seems, have variable markings of light fur on their throats and chests. So variable, in fact, that each wolverine, if looked at closely, has a unique chest pattern. And therefore, with the right picture, we could tell them apart. A brilliant idea, truly, but in practice… It would seem that getting any picture of a wolverine would be a lucky convergence of circumstance, but to get a specific picture—a wolverine in a specific pose, well, it seems like wishful thinking. But then again, most great accomplishments start as silly dreams. The credit for the accomplishment of this silly dream lies to the north, with Magoun and her team of field people, who took an idea—getting pictures of wolverine chests—and made it happen. We’ve just followed their lead. But it is still exciting.

It is the radio call we’ve been waiting for all season.

Adam and I linger beside the truck, waiting to unload a couple of snowmobiles and get on with our assignment for the day—setting up our first camera station. But our attention is focused on the Forest Service radio. Waiting. Sherrie and John are up Twisp River checking on two wolverine traps that emit a “closed” signal from their radio transmitters. They have checked the first, and found it occupied by a marten. They should be at the second trap at any moment.

After fifteen minutes of fidgeting, kicking at snow and checking our watches, the radio comes to life. We eavesdrop on static and garbled voices, and finally make out words that change our day. There’s a wolverine in the trap. Our afternoon becomes more interesting. And longer. We pile back into the truck and drag our snowmobiles toward Twisp River.

This winter, ten or more Forest Service employees and volunteers tend ten wolverine traps on the outskirts of the North Cascades. We’ve been at it for two weeks already—replacing bait, checking the function of the traps, dealing with radio transmitter malfunctions and shoveling snow off of the traps. The status of the traps is checked each morning with radio receivers. We physically inspect and test the traps every three days or so. It is a fair amount of work, and the crew comes home each afternoon a bit weary and smelling of snowmobile exhaust. So far we have caught nothing but martens.

Friday, April 17th I tagged along with Amy Brown and Orlando Garcia, assisting with the Kulshan Creek Neighborhood Program. With the arrival of spring and the return of many migratory birds Amy had a wonderful afternoon planned, which included talking about our feathered friends and playing games. As we drove into the Kulshan Creek neighborhood the clouds that had been hanging around all day dissipated and the sun broke free.

This guest posting is written by Orlando Garcia, information ranger for the US Forest Service. He is working with the Kulshan Creek Neighborhood Program as part of his coursework at Skagit Valley College.

I spent the day with the Kulshan Creek Kids last week. Carolyn Waters from North Cascades Institute had an activity planned for the kids, which involved planting tomatoes, cilantro, or green peppers. What Carolyn had in mind was to have the Kulshan Creek Kids plant vegetables and play a game to learn what was involved in the process of plant growth. With that plan in mind, Carolyn and I jumped into a vehicle and took off for the Kulshan Creek Community and met with Lee Whitford, Institute Naturalist.
