The link to those SAR stories is an incredible find. Thanks again. I learned a few valuable things about how to survive being lost (in general) as I read:
1) After 2-3 days, if you don't consume water your organs start to fail, so conserve water, drink pee, and find water in dense brush areas when you can.
2) It seems like most watersheds run N/S, but most populated areas are faster reached W/E. So, always head W/E when you can using the sun's location as a compass/guide, even if the N/S route seems easier to travel.
3) If lost, move around at dawn/dusk and in moonlight if possible, and take shade during the hottest part of the day.
4) Someone will come look for you if you don't show up when you are supposed to and IF someone knows where you went. So always share your itinerary - just in case.
5) STOP walking and wait for help if someone knows where you are hiking.
6) Wile hiking around, always leave behind some sort of marking of where you have been. Make a rock cairn (stack rocks), break a branch, write words and arrows in the dirt, all or any of those. That way, if you are walking in circles you will know right away. Or if you are lost, it will help trackers find you. And marking your path with these ways does not harm the environment.
