Yes, a compass is a good idea. In the above example, I could have walked downhill because I knew there was a road at the bottom. I would have wound up about 10 miles from my pickup. The terrain was in the mountains but was uncharacteristically flat, which is one reason why the elk liked it. It was just unsettling. My dad and I backpacked into the Scapegoat 40 years ago. We had compass and map and knew how to use them. One morning, we woke to 6 inches of snow and it was still snowing-hard. We had a couple of days left but decided to pack up and walk out. Somehow, we missed a fork in the trail. In our defense, there was no improved trail to the lake we had gone to, just a faint mile and a half track down the drainage to the main trail. When the snow slowed down a little we could see that we were not where we thought we were. I wasn’t exactly frightened because we had lots of food and gear and would have been fine until things cleared up. It was again, unsettling, to be so sure and then find out we were so wrong, so we backtracked to the fork and walked out. We caught 50 fish each for each of the two days we were at the lake. So it was worth it. It was mid-July.
