An analysis of the soundings. The estimated resistivity, in ohm-m, is shown for the three strata which were detected by the soundings. Diagonal hatching indicates the lowest resistivity, while the dotted pattern shows the highest resistivity; intermediate resistivity is marked with an X pattern. Sounding 1 was not analyzed using these same procedures because of the effect of the topography of mound 68.
