me neither, it seems like the people there are peaceful, open minded, or spiritual, and the view is just stunning:

some say the earths magnetic "points" is where the magnetic field is concentrated at, and then flows towards the rest of the earth.
so the more concentrated, the stronger the magnetic field.
now i will remind you that our consciousness is electrical, maybe those people are spiritual because of the affect of magnetism on their consciousness.
or maybe since people used to use a magnetic compass, so maybe while in sea or in air, the traveler followed the compass towards the wrong way and
simply never came back because to the person, being stuck in the middle of nowhere is completely helpless/hopeless situation.
i mean these are just my own theories attempting to expand everybodys mind to what the real reason could be, since we dont have an answer, its logical to say the answer could just be anything and everything.
