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.

This report follows a rotary-wing high sensitivity radiometric and magnetic survey that was flown covering a portion of the Lakeview Oregon area.

Final report documenting a high-sensitivity airborne radiometric and magnetic survey of the Vancouver, The Dalles, Pendleton, Walla Walla, Yakima, and Hoquiam quadrangles including background information, a description of methods, data reduction and analysis, and data presented in maps, tables, and graphical forms.

Second volume of a report documenting a high-sensitivity airborne radiometric and magnetic survey of the The Dalles quadrangle including results of data interpretation, significance factor profile maps, stacked profiles, and histograms.

Report documenting results of an airborne high-sensitivity gamma-ray spectrometer and magnetometer survey of the Roseburg quadrangle in Oregon, including data acquisition methods, a summary of data and outline of data presentation, area geology, and interpretation of results.

Report documenting results of an airborne high-sensitivity gamma-ray spectrometer and magnetometer survey of the Coos Bay quadrangle in Oregon, including data acquisition methods, a summary of data and outline of data presentation, area geology, and interpretation of results.

Final report of the airborne gamma ray and total magnetic field survey for the Grangeville quadrangle, Idaho-Oregon-Washington. Sections I through IV of this report present information and results associated with this specific survey. Section V gives the data acquisition and the processing procedures.

Report documenting results of an airborne high-sensitivity gamma-ray spectrometer and magnetometer survey of the Medford quadrangle in Oregon, including data acquisition methods, a summary of data and outline of data presentation, area geology, and interpretation of results.

The following report the the first set that documents the results of the airborne gamma radiation and total magnetic field survey flown for the Jordan Valley quadrangle in Oregon and Idaho in 1979.

The following report the the first set that documents the results of the airborne gamma radiation and total magnetic field survey flown for the Adel quadrangle in Ohio in 1979.

From introduction: The data presented here are reconnaissance data intended for use in identifying broad areas for further study. While care has been taken to provide reliable sampling and analyses, verification of individual analyses is beyond the scope of this report. The data should be viewed statistically because "one-point anomalies" may be misleading. Regional trends, however, should be reliable. This report is one of a series presenting data obtained by SRL reconnaissance.

Results of the Lakeview detailed geochemical survey are reported. Field and laboratory data are reported for 231 groundwater, 881 stream sediment, and 303 stream water samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the area is provided and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.

Second report documenting results of an airborne high-sensitivity gamma-ray spectrometer and magnetometer survey of the Medford quadrangle in Oregon, including histograms and multi parameter profiles, with anomaly maps and flight path maps.

Second report documenting results of an airborne high-sensitivity gamma-ray spectrometer and magnetometer survey of the Roseburg quadrangle in Oregon, including histograms and multi parameter profiles, with anomaly maps and flight path maps.

Second report documenting results of an airborne high-sensitivity gamma-ray spectrometer and magnetometer survey of the Coos Bay quadrangle in Oregon, including histograms and multi parameter profiles, with anomaly maps and flight path maps.

The first volume of a report regarding an airborne gamma-ray spectrometer and magnetometer of the Crescent Quadrangle, the Burns Quadrangle, the Canyon City Quadrangle, the Bend Quadrangle, and the Salem Quadrangle in Oregon. "Volume I contains a description of the systems used in the survey, a discussion of the calibration of, the data processing procedures, the data display format, the interpretation rationale, and the interpretation methodology."
