This paper presents two case histories utilizing remote sensing earth resistivity equipment to target subsurface massive ice locations. In one case, a number of probe locations were made using increasing 'a' spacings (soundings). Field data were analyzed using a computer program for data reduction and iso-resistivity contours were plotted for various planes. In the next case, the target area was in an active river and only two soundings were utilized. In both cases, cumulative plots were used for depth predictions. Electrical earth resistivity worked well for the early phase of each geotechnical investigation.
