We don't have much information to go on.

Generally, if you are on a trail, you stay on it. Or you head toward a stream where you have water and visibility overhead.

But if you get off the trail and get turned around, in that PNW bush, you have one heck of a problem. From the little bit I've seen, you could set a truck on fire and it would hardly penetrate the canopy. It's a tough place to signal.

There's also the psychology of being stranded/turned around. I could sit and wait for a few days, but I think the pressure to "do something" would be overwhelming after a while. In an ideal situation, the information you left with a responsible person helps you as much as the searchers, by reducing the temptation you face to go thrashing through the bush no matter what.

I'm still hoping for the best.
