One way to find out what's down there. Core sample. A REAL Core sample from the Core. I am still entertaining the possibility that the atmosphere of earth is responsible for the earth's magnetic field. Earth's core may be iron, but it needn't be magnetized, and even though rotating needn't generate a mag field by any means including cutting flux lines emanating from the sun or Jupiter.

Could be something to consider.
