Funding was provided by the Alaska State Legislature.
This airborne geophysical survey was acquired to gather geologic information to assess the geologic hazards, construction materials, and mineral potential on the Alaska Highway corridor in east-central Alaska. The geophysical information acquired helps provide information on conductive overburden, potential construction materials, permafrost, fractures and faulting, and other information. Prospects within the survey area include Road Metal, Triple Z (ASARCO), and Discovery Zone. In addition, these data are to assist geologic mapping in the region.
