We have little appreciation of the immense electrical currents that flow through the rock formations beneath our feet. These "telluric" currents are primarily those induced by the earth's changing magnetic field, as it is affected by the solar wind. Telluric cur-rents do not flow uniformly through the earth's crust. Rather, they seek out low resistance rocks, in accordance with Ohm's Law. Such current concentrations can be detected at the surface with magnetometers.
The present paper announces the discovery of a regional telluric current flowing in the vicinity of the San Francisco Peaks volcanic field in Arizona. The shallow part of the current flows in an unidentifiable "geoelectrical" structure not more than 10 kilometers below the surface. There are no surface hints as to what this geoelectrical structure could be.

Comment. Similar anomalous magnetic fields exist in many areas, indicating a vast subterranean system of poorly understood geoelectrical structures. Some of the channeled earth currents are man-made, being the return paths in electrical power transmission systems. The return paths may be far-removed from the actual power lines because they tend to follow the geoelectrical structures.
