From Introduction: "The Baker Quadrangle, in east-central Oregon and west-central Idaho (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits."

Appendices containing data on uranium availability in the Baker Quadrangle to accompany a report on U.S. uranium resources in Oregon and Idaho.

From Introduction: "The Jordan Valley Quadrangle (Fig. 1), southeastern Oregon and southwestern Idaho, was evaluated to define areas that have geologic environments favorable for uranium deposits."

This sample file contains 346 records for Oregon. The records contain data on location, sample description, analysis type, collection condition, flow rates, and chemical and physical properties of the fluid. Stable and radioactive isotope data are occasionally available. (ACR)

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.

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

From Introduction: "The Klamath Falls Quadrangle, in south-central Oregon between lat 42º and 43º N. and long 120º and 122º W. (Fig. 1), was evaluated to identify geologic environments and delineate areas with characteristics favorable for the occurrence of uranium deposits."

From Introduction: "The Vya 2º quadrangle (Fig. 1), in northwestern Nevada and small portions of California and Oregon, was evaluated to identify geologic environments and to delineate areas that have characteristics favorable for uranium deposits. Reconnaissance sampling in the Vya Quadrangle began in 1978, but final evaluation of the uranium favorability of the quadrangle was began in 1978, but final evaluation of the uranium favorability of the quadrangle was begun in June 1980."

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.

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: Of the various hydrologic hazards in our environment, the mass movement of earth material caused by excess moisture can be one of the most destructive. These events often go unnoticed because they occur in unpopulated mountainous terrain during winter seasons. This was not the case in December 1964, when a major debris flow occurred in the Cave Creek drainage of the Oregon Caves National Monument. In March 1982, the National Park Service (NPS) requested a study be made to appraise the possibility of a recurrence of the 1964 debris flow in the interest of safeguarding the public and employees of the National Park Service.

Report issued by the U.S. Bureau of Mines discussing a workshop held on the techniques for measurement of thermodynamic properties. As stated in the abstract, "this information circular comprises the proceedings of the workshop and includes the texts of papers presented and discussion by attendees" (p. 1). This report includes tables, illustrations, and photographs.

From introduction: This study was made in cooperation with the planning departments of Wasco and Hood River Counties, The purposes of this report are (1) to describe the occurrence, movement, availability, and quality of ground water in the basin; and (2) to assess, where possible, the extent, thickness, hydrologic boundaries, and hydraulic properties of the principal aquifers.

From purpose and scope: This report describes methods for estimating the magnitude and frequency of floods at ungaged sites on streams with unregulated flow in eastern Oregon. The purpose is to provide a method to estimate flood magnitude and frequency and to present the supporting data. The report is based on data from nearly all unregulated streams (or data from regulated streams prior to their regulation) where gaging stations have been operated.

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."
