A resistivity pseudosection of line 1. Small circles locate the measurements. The soil at the surface has a high resistivity, while the deeper soil has lower resistivity. The electrodes were in a pole-pole configuration. The current reference electrode was about 50 m to the north, while the voltage reference was about 25 m north and 25 m west of the survey area.
