Estimated Altitude of the Top of the Uppermost Unit of Fine-Grained Sediment within the Wood River Valley aquifer system, South-Central Idaho

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This dataset is the estimated altitude of the top of the uppermost fine-grained sediment within the Wood River Valley aquifer system. This map was compiled by describing the estimated altitude of the top of the fine-grained sediment from about 160 well-driller reports for boreholes drilled within the area of the approximate extent of the confined aquifer. A surface was generated using kriging of the point data. This dataset was created in support of [...]
