There are some good lessons in what you shouldn't do, perhaps not intended so, but still interesting.
We don't have many forest fires here in Norway, but we do have very harsh winters. Every year a family or group of people are trapped in a blizzard and die. And most of it could have been avoided by following the "Norwegain Mountain Code"[1], which I imagine is similar all over the world. Turning back before it's too late, seeking shelter, and not exhausting yourself when you realize that you're in trouble. I'd be very worried if people in my group started getting nauseous. That's when you start making those deadly mistakes.
Turning back the millisecond the danger is known.
There are certain warning signs that should not be ignored. Each group sport has them and over time you learn to follow some protocols or you have to find yourself some new friends.
For cycling in the Midwest, it's lightning strikes. There is no place to shelter and the storm can move faster than you can, so after the first strike, everyone is counting time to see if they're getting closer. If they are, you turn back for shelter, even if home is in front of you. Most of the time that's a foreshortened outing, but on one occasion we had to double back to the half-way point and wait it out. Even though that meant a lot more time out there and a longer route than we planned.
When they mentioned the black smoke and continuing forward, it made me angry. I had a sudden flash of the conversation that had us holing up, dripping wet, in a little town in the middle of nowhere. It was clear who was going to win the argument before we turned around, even though it wasn't what we wanted to hear. We all knew the rules, clearly these people don't.
(Over the years I've come to recognize how above average that group was in organization skills, but one should still aim for a solid grip of basic safety routines from inclement weather to common injuries and avoiding/treating heat stroke and exhaustion)
Then again, wildfires can move 100 miles in a day, about 10x faster than a human. Like a viral pandemic, you have to make decisions before it feels dire. It sounded like though that they got enough information early on via satellite communicator to realize it wasn't an immediate threat. I think the author is guilty of mild over-dramatization.
With a full pack, unacclimated, making 10+ miles is a pretty good day. 13 miles outrunning a forest fire is respectable.
Also, they had 7 days to complete the rest of their hike. I suspect the stats for the hike out weren't too difficult, but the cumulative effects were.
They had a weeklong backpacking trip planned, hiked to where they thought they would start it, encountered smoke and potential fire, and had to hike back out. Leisurely. Enough to get a solid 9 hours of sleep. Doesn't quite qualify as the life-in-jeopardy kind of event that the polish and presentation of the blog make you think you're in for.
I'm a little more interested to hear about the folks who were actually in danger and barely escaped.
