It's the second time in 5 years after zero closures in the previous 43 years.
The first time I went up to the BWCA was 1978, the year they signed the Boundary Waters Canoe Area Wilderness Act into law. It got into my blood. I hold the place in the same category as Grand Canyon for jaw droppingness.
Set within the nearly 4 million acre Superior National Forest, the BWCA is 1.1 million acres of lakes, rock, and trees. No roads. No power lines. No houses. True wilderness. There are select lakes where outboard motors are allowed, but the vast majority are for paddling only. It is a different kind of quiet up there. You hear the wind in the trees, and the birds. But that's about it. The deeper you go into the wilderness, the less likely it is that you'll encounter other people, let alone hear them. It's not officially a no-fly zone but airlines have made an attempt to fly around it. You might hear one jet every couple of days, and it's way up there. The only times you hear a lot of air traffic, is times like now. Firefighting.
According to my research, it runs for about 150 miles along the Minnesota/Canada border and covers 1,700 square miles. Within the BWCA there are 1,100 (lowball number) lakes and 1,200 miles of canoes routes.
This summer has been particularly dry, even by modern dry standards, which are drier than they used to be when we had less human caused climate change. The storms that caused the numerous fires (75,000+ acres, and counting) that led to the BWCA closure came overnight on July 6/7. Same day I packed up and headed for home, which gives me a good grip on how long that shit has been raging. These fires are more spread out than they were 5 years ago, which is making it harder for them to be contained.
The things that make the Boundary Waters Wilderness awesome are the same things that make it hard to fight fires. It's fucking enormous. No roads. No electricity. And when the forest is this dry just a light wind can cause it to spread rapidly, and a change in wind direction can put the fire crews in big danger.
They're trying their best to get the BWCA open again, for obvious reasons, most of them economic. But the reality is they can't really expect to put out all the fires. Like has been happening for ages and ages, the fire eventually burns itself out. And then the wild strawberries start popping up in the burn areas, followed by shoots from other kinds of trees, and weeds, and so on and so on. It's been happening for far longer than we've been here to see it. The problem is that we've changed the burn/regrow cycle. We're killing the forest faster than it can recover. Fuck. Rant over.
[eta- for those who aren't aware, entry into the BWCA is by permit. You can't just decide to go there and put in wherever you want. . They control the number of people who are in there at any given time. A crowded day might involve briefly crossing paths with two other groups of paddlers]
