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.

The following data report presents results of ground water and stream/surface sediment reconnaissance in the Pocatello quadrangle, Idaho.
