| Abstract: | Data from a direct current resistivity survey and geologic logs from boreholes were used to map the top of permafrost at
a remote air force installation in Alaska. This study resulted from a remedial investigation that was conducted at Eielson
Air Force Base near Fairbanks, Alaska, under the federal Comprehensive Environmental Response, Compensation, and Liability
Act (CERCLA) regulations. The depth and continuity of the permafrost was important in determining the fate of petroleum contamination
that was inadvertently discharged to the ground during earlier air force operations. The results indicate that the top of
permafrost forms a highly irregular surface. In general, however, the top of permafrost forms a diagonal ridge at the center
of the contour grid that is bordered on each side by troughs.
