I am revisiting Sedona, AZ and am joined by my brother and sister-in-law. I am doing some photography, but I am more focused on hosting their visit.
Magnetometers can measure the earth's magnetic field with great precision, thus can measure differences in the magnetic field. So can a compass, but with far less precision. A compass is, however, much more sensitive to the earth's magnetic field than we are, which is why we have them and use them. The variations in the earth's magnetic field near the red rocks are not enough to noticeably affect a compass. Further, any such shift would be to the horizontal nature of the field. It is certainly not turned vertical by such minute amounts of iron, regardless of the shapes of the rocks.
That does NOT mean that it is a force of nature, an energy vortex as it were. I think it is a life force within us, which gets trapped by the trammels of our culture and civilization. If we hear about, and believe in such things as energy vortexes, and we travel to a place like Sedona, then climb to the top of a dome hoping and expecting to experience an energy vortex, we will feel a flowing of energy and we will believe that it comes from an external source, perhaps the realignment of the earth's magnetic field. Our psyche will assure that our expectations and preconceptions are fulfilled. If we have a basic understanding of science and come to Sedona with no expectations of energy vortexes, we can still climb to the top of a dome and sit and allow ourselves to feel renewed without the need for an imaginary energy vortex. I believe that that such renewal comes from inside, not from external energy vortexes.
Are there energy vortexes here? Science can almost never prove a negative, so I can not say no. All I can say is that there is no indication, at least to me, that there are such, either here or anywhere. Maybe someday, science will find some measurable force that travels upward through the earth, and is focused into a vortex by a dome of red rock. Until then, I will be content with simply enjoying the beauty that is around me, without the need to invest it with some supernatural energy fields.
If you want to feel renewed, get out to nature and immerse yourselves in it. If you want to experience a more intense concentration of the earth's magnetic field, get in your car. That, at least, has enough ferrous concentration to affect a compass needle.
Me? I will just relax and enjoy the beauty.
