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.

This abbreviated data report presents results of ground water and stream sediment reconnaissance in the Mount Spokane quadrangle in eastern Washington and northeastern Idaho

Tabulated data presenting the results of field measurements and elemental analyses for ground and surface water samples collected from the Mount Spokane quadrangle in eastern Washington and northwestern Idaho. Data from ground water sites includes water chemistry measurements (pH, conductivity, and alkalinity), physical measurements, where applicable (water temperature, well description, and scintillometer reading), and elemental analyses (U, Al, Br, Cl, Dy, F, Mg, Mn, Na, and V). Helium analyses are given for ground water. Data from surface water sites include water quality measurements (pH, conductivity, and alkalinity) and elemental analyses (U, Al, Br, Cl, Dy, F, Mg, Mn, Na, and V). (see pages 6-9 of report).

Charts presenting the results of ground water and stream sediment reconnaissance in the Mount Spokane quadrangle in eastern Washington and northwestern Idaho. Stream sediment samples were taken at 225 sites. Data from sediment sites include water chemistry measurements from sites where water was available (pH, conductivity, and alkalinity), and elemental analyses for sediment samples (U, Th, Hf, Al, Ce, Dy, Eu, Fe, La, Lu, Mn, Na, Sc, Sm, Ti, V, and Yb). Sample site descriptors (stream characteristics, vegetation, etc.) are also tabulated. Areal distribution maps, histograms, and cumulative frequency plots for the above elements, log U/Th, log U/Hf, log U/(Th + Hf), and scintillometer readings at sediment sample sites are included.

From Introduction: "The Sandpoint Quadrangle (Fig. 1) was evaluated to define areas with geologic environments favorable for uranium deposits. Environments were evaluated on the basis of surface investigations because few subsurface data were available."

Appendices containing data on uranium availability and sample analyses to accompany a report on U.S. uranium resources in the Sandpoint Quadrangle, Washington, Idaho, and Montana.
