What visions does the name “experimental forest” evoke in your mind? Other than areas of cut timber, Fraser Experimental Forest looks like a normal forest to me. There are lots of evergreen trees. So what’s so experimental about it?
I imagined that new hybrid species might be planted in areas to see if they’re hardier. Do they stand up to pine beetles that are ravaging thousands of acres in Colorado? Do these varieties thrive on less water? Are they more resistant to forest fires? Perhaps it has nothing to do with the trees. Maybe new animal species are introduced to the forest to see whether they survive?
I have a book indicating winter trails which don’t allow machinery (snowmobiles), making them perfect for cross-country skiing and snowshoeing. Several featured trails are located in this 36 square mile forest. We first tried snowshoeing in Fraser Experimental Forest (near Winter Park, CO) a year or two ago. After trudging upward for a long time, we finally got to the marker that would lead us downhill – for more than twice the distance we’d already traversed. There wasn’t enough daylight left, so we turned around. Thankfully, we have a snowshoeing rule: go uphill first, so the return is easier and faster. This rule has served us quite well! We wondered whether we were actually on the trail we’d intended. The turn around point seemed a lot further than the book described.
So this time, we picked a different trail, and took along our GPS. What a nice change to know exactly how far we hiked! Well, once again, we didn’t manage to follow the book. We were supposed to go counter-clockwise around the loop. We went clockwise. So unsurprisingly, we never found the major 4-way intersection at the 1.5 mile point!
Along the way, we learned that our imagination was rather limited regarding the meaning of “experimental forest.” We encountered this sign. A little further along the trail (summer road), we encountered a clearing on the same side of the road. The cleared area was roped off, as if the rope was an impervious boundary for any radiation. You’re fine where you are but cross under the rope and you’ll get radiation poisoning! Um…right. There were a couple of obvious little buildings on the other side of the road, down in the woods, with large tanks. What, do they store their emergency radiation suits there? Oops, forgot my suit today, let me just grab one that the mice have been nesting in. The holes won’t matter…much. At least the hantavirus carried by mice pales in comparison to radiation.
Of course, that little encounter sparked my curiosity enough to look up the forest’s website when I got home. The official site makes no obvious mention of the radiation area. It does say the experiments have been ongoing since the 1930s and that temperatures and water levels are recorded. Whoopee. OK, so the site did expand my vocabulary as well: silviculture is the growing and cultivation of trees. So my original thoughts on what an experimental forest (here’s the overall USFS site for experimental forests in general) might be used to study wasn’t too far off. But what about the radiation?
I searched “Fraser experimental forest radiation” but all the top results regarded solar radiation. Somehow, I just don’t think a wooded area would be closed as a radiation hazard for solar radiation. If that were the case, every high altitude, typically sunny area would be closed off! That includes most of the state of Colorado. Mining is a significant industry in Colorado’s Rocky Mountains, and uranium is one of the elements extracted – but from my limited research, uranium mining is done in the western portion of the state, not along the Continental Divide where we snowshoed. There’s a nearby molybdenum mine, but molybdenum isn’t radioactive. Besides, the mine isn’t exactly next door to the experimental forest. Several miles separate them.
So the mystery remains: what the heck is radioactive out in the forest? Looks like we might have to start hiking the area in the summer to see what else we can figure out. Until then, maybe we’ll pay better attention to the guidebook, buy a map, and enjoy the area on snowshoes.
Incidentally, this was Kermode’s first snowshoe! Last year she was too young to take long hikes, and too heavy to carry. She did very well. She’s well used to her booties, but this was her first hike in them. She didn’t mind the snow packed trail, but she preferred to bunny hop through the deeper powder on the side of the trail. She was silly, entertaining, and an absolute delight on the trail. Glacier was much more regal while walking, but stopped at every opportunity to make puppy snow angels. So we’re eager to take them snowshoeing again. Tomorrow, perhaps?
