They’re verrrry fortunate to even be alive.
I know that country where they were found like the back of my hand. Born, raised, hunted and fished there for years with my father as a kid. That area where they were found is outright fricken’ brutal even in the summertime. It’s the country that’s sung about in the song: “Tombstone Every Mile” song by Dick Curless....LOL.
FWIW, we still have family that live near there. Two weeks ago this past Saturday, they had a nice little 23 mph breeze straight out of the NE, -16 degrees below zero, with a -45 degree chill factor. Two 50-year old women without a clue wouldn’t last long in it. They’re lucky.
Stay in the car ....maybe bank it with snow. Just being Mainiacs probably helped. We had a high-profile Asian techie from SF(?) follow his GPS past a barrier on a logging road. Ended up dying in the woods. His wife and kid were found alive at the car.
