What is the term for that phenomenon when someone in wilderness start experiencing a strange situation? When,
I don't know what it is called, or even anyone of us has experienced it. But, I have had a taste of what happens.
In less than a couple of years ago, I was on a solo trek, a region that wasn't known too well (I must admit) to me. See the images from the GPS track that I was logging.
Few points to note:
I believe this is called walking in circles :)
What happens is that is that without a compass or GPS, you tend to head to one side instead of going straight. Eventually you will complete the circle and head back around the other way.
If you have ever turned the tracking mode on a GPS and then left it in your pack, while navigating without it in a dense forest without reference points, the effect will become apparent. It's all but impossible to walk in a straight line without a point of reference or a navigation device.
"All those signals have very small errors," Souman says. In general, that leads people in a random, meandering path, Souman says. But occasionally, the errors in a particular direction build up, leading us to walk in circles.
When people can see where they're going, however, it's a different story. Souman and his colleagues also tracked volunteers as they walked without blindfolds in two unfamiliar environments: a forest in Germany, and, thanks to a junket arranged by Kopfball, in the Sahara desert in Tunisia. In the forest, people again walked in circles--but only on cloudy days. When the sun was visible, they could walk in a more or less straight line for several hours.
Also, human trails will go straight, but animal trails will wander, that might have something to do with it.
On the other hand, I have seen plenty of people who were so worried of getting lost that they never went anywhere in the first place. This is a good reminder that getting lost isn't the end of the world.
