I have been "lost" once and it was terrifying. Not in a spooky sense, but in a deep, gut wrenching dread sense. I posted a story earlier in the thread about losing a cow elk when I was 17, muzzleloader hunting (my first kill, which was a tough way to start).
So the whole story is this. We went for an evening hunt, drove up to the top of this meadow and walked a little game trail down into the meadow in about 2 feet of snow (trail was churned up from elk). The trail went in a J shape, which becomes important later in the story. I saw a cow elk (legal) at about 80 yards in the heavy snow, and my dad said it was good to shoot. I knew I'd hit her good, but we were right at last light. We stayed there for about 15 minutes waiting, and by the time we moved to look for blood, the snow had already filled in most of her tracks. It was dark enough I could barely tell where she had been standing when I shot her. We couldn't find good sign, but it was cold as heck so we decided to walk back out and come back in the morning. We hadn't brought packs with us since we were just going on a quick jaunt (lesson learned).
With the excitement, we'd forgotten that the game trail had made a big J shape, and we weren't directly below the truck but about 1/2 mile North of it. We went straight uphill, and just... kept going and going. No packs, no light, no food or water. In good clothes, but that's it. We had a Garmin GPS but it had been giving us weird directions all weekend and we didn't trust it anymore. It kept telling us that the truck was BEHIND us somehow, which we knew wasn't true (we were wrong). We ended up using the GPS backlight as our flashlight, which wasn't worth much.
So we're climbing straight up hill in knee deep snow that's getting deeper, my dad is starting to flag hard so I'm carrying both rifle, and picking him up every few steps when he stumbles. I kept seeing wide, flat, white shapes ahead of us that I assumed was the road, and every time we got closer it turned out to be a log on it's side covered in snow. That was the most soul crushing thing in that moment, to have the hope of the road turn into another obstacle, over and over again (10-12 times).
Finally, 2 hours in, we stopped and agreed to try and follow the GPS cause what we were doing just wasn't going to work. It had been telling us the road paralleled our travel path heading uphill and we didn't believe it, because we thought this road side-hilled for a longer distance. So we walked 50 **** feet to the left and hit the road. We had paralleled that stupid thing the whole way, and had zero clue because it was thick, brushy, and dark.
In his relief and haste, my dad stepped off the bank onto the road, which wasn't a great call because the bank turned out to be about 6 feet above the road. So he ragdolled down the frozen road a bit while I tried chasing after him, juggling a pair of 58" long muzzleloaders (I'm 66" tall, which make maneuvering those things a beotch). Finally got my dad on his feet, and we made it back to the truck just as our rescue party (the rest of the camp) came rolling around the corner looking for us. The relief of seeing the truck was amazing. I'll never forget the first look of it, actually. I couldn't see the truck, but I could see a little flashing red light from the cigarette lighter charging port that was plugged in to the dash.
I have never once left my truck without a full pack since that day. It could be a 10 minute jaunt, and I will have 90oz of water, 3 days of food, clothes, a bivvy, the whole works. Most days my hunting pack is 30 pounds at least just in extra gear. Last year I had an elk chase turn into an 8 hour hike, well past dark, no one knew where I was, and I was extremely comforted to know that if I had to bed down somewhere I had everything I could possibly need to survive. It made all the years of carrying the heavy pack seem very worthwhile.
