Introduction: This report presents engineering details, statistics, individual borehole histories, and geophysical logs of the eleven holes drilled in the McDermitt caldera project during the 1981 drilling program. General information is presented regarding specific problems, including weather and logistics. A separate geologic report is being prepared and will be available through the Bendix Field Engineering Corporation Technical Library in the near future.

The following report presents the results of the geochemical reconnaissance sampling in the Lovelock quadrangle, Nevada.

The following data report presents results of ground water and stream sediment reconnaissance in the Walker Lake quadrangle, California and Nevada.

Final report documenting a high-sensitivity airborne gamma radiation and magnetic field survey of the Lovelock National Topographic Map segment (NK 11-10 quadrangle) including a description of the program and results.
