re: If you ever get completely lost in the wild the best advice is to stop and stay put

Sounds like you were in the Boy Scouts because that's what they recommend.

Before you go, however you're supposed to Always tell someone exactly where you're going and when you'll be back, Be prepared by educating yourself on the local conditions and carry appropriate gear, and Carry a survival kit (shelter, fire, signaling).

If you did at least A then you should be good to stay put. They suggest you STOP. Stop, Think, Observe, and Plan. Stop, stay calm. Eat and drink something. Make a fire. If someone's injured then you have to decide if it's serious enough to risk leaving (stay or go, fast or slow).

That's all I got.
