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.

From abstract: Jurassic ammonites of late Bathonian to middle Callovian Age have been found in 12,000-13,000 feet (3,660-3,960 m) of strata exposed in the area near and south of Izee and Seneca in east-central Oregon. Ammonites of early Callovian Age and possibly also late Bathonian Age occur in several hundred feet of black shale exposed along Dennett Creek near Mineral, Idaho. Early Callovian ammonites also occur in similar black shale exposed on the Oregon side of Snake River Canyon about 32 miles (52 km) south of the northeast corner of Oregon.

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.

Supplementary data containing geophysical logs to accompany an engineering report on the McDermitt Caladera Drilling Project in Nevada and Oregon.

Supplementary analytical data containing elemental concentration data in surface sediment samples and ground water samples, in addition to areal distribution maps, histograms, and cumulative frequency plots. Also included is site location data for surface and ground water samples, and a user's guide. This data accompanies a report on hydrogeochemical and stream sediment reconnaissance of the Baker 1° x 2° NTMS Area, Oregon and Idaho.

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.
