Hi I currently live here in Blythe, California my hometown. Born and raised here but unfortunately I never have made the trip to go see the intaglios. Very interesting it was considered to have a vortex perhaps in our area. I don’t know nothing about them. But have to say that there has always been a weird energy here. Very high polarity of the light and dark. We have always had tons of Ufo sightings and activity. And strangely there has been a pattern of people gone missing.
