Revision History for U.S. Geological Survey Scientific Investigations Report 2015–5175 By Joseph M. Fenelon, Keith J. Halford, and Michael T. Moreo Delineation of the Pahute Mesa–Oasis Valley Groundwater Basin, Nevada ----------------------------------------------------- Posted online January 22, 2016 ----------------------------------------------------- Revised and reposted May 12, 2016 On plate 1, the southeastern boundary of the Pahute Mesa–Oasis Valley groundwater basin was modified slightly to match the model boundary shown on figure 5 of the report. On plate 1, water-level contours east of Death Valley were revised. Contour lines “328 (100)” through “1,969 (600)” were truncated near Highway 190 so they no longer extend south. On plate 1, two groundwater flow arrows were deleted: one east of Death Valley Junction and one east of Shoshone.
