Abstract: Reconnaissance of Red Rock Valley was begun on December 10, 1953, and completed on February 11, 1954. The mines in the region were investigated and all exposures of Salt Wash were walked. Paleostream directions and alterations of the sandstones were observed and recorded on a base map. No important new mineralization was discovered-and the area is considered to be of no commercial significance if judged by the outcrops alone. However, a vast amount of Salt Wash lies at slight depth directly to the east of the investigated area.

From introduction: This volume contains information and survey results pertaining specifically to the Saint Johns NTMS 1:250,000 scale Quadrangle, Arizona and New Mexico, one of a group of 12 such quadrangles in Arizona, Idaho, Montana, New Mexico, South Dakota, and Washington included in an aerial radiometric and magnetic reconnaissance survey. General information concerning the instrumentation and methods used in data acquisition, processing, and interpretation is presented in Volume 1 of this final report.

Introduction: A reconnaissance of the Black Brush property was made by geologists of the Atomic Energy Commission in March, 1955. This anomalous area was located by an earlier airborne radiometric survey. the examination consisted of preliminary sampling and surface and underground radiometric traversing.

Data collected as part of a report on the Clifton New Mexico quadrangle including laboratory data on waters and sediments as well as field data.

Supplementary data containing analyses of ground water samples, surface sediment samples, stream water samples, site location maps, and a user's guide to accompany a report on hydrogeochemical and stream sediment reconnaissance in the Phoenix 1° x 2° NTMS Area, California and Arizona.

From Abstract: "Field and laboratory data are presented for 451 water samples and 900 sediment samples from the Clifton Quadrangle, New Mexico; Arizona."

From abstract: This abbreviated data report presents results of ground water and stream/surface sediment reconnaissance in the National Topographic Map Series (NTMS) Phoenix 10 x 2 quadrangle. Surface sediment samples were collected at 1388 sites, at a target sampling density of one site per 15 square kilometers (6 square miles). Ground water samples were collected at 155 sites. Neutron activation analysis (NAA) results are given for uranium and 16 other elements in sediments, and for uranium and 9 other elements in ground water. Mass spectrometry results are given for helium in ground water. Field measurements and observations are reported for each site. Analytical data and field measurements are presented in tables and maps.

Appendix containing tables to accompany a report on aerial radiometric and magnetic reconnaissance survey of St. Johns Quadrangle.

Appendix containing single-record and averaged-record data listings to accompany a report on aerial radiometric and magnetic reconnaissance of the Ritzville Quadrangle.

From introduction: This report is a status report to complete present contract obligations and is submitted in lieu of a Final Report. A Final Report is not feasible especially until complete analyses and statistical treatment of all of the 436 rock chip, 2 soil-rock and 90 water samples, a total of 528 samples submitted by the partners to Union Carbide, Oak Ridge, Tennessee, plus remaining analyses to be run by BFEC's Grand Junction Laboratory become available and other recommendations and necessities are done. See subsequent section of this report titled: "Recommendations For Work Needed to Complete Final Report". A Final Report may be prepared by the partners if supplemental funds for such work and for completion of the analyses and their statistical treatment ever become available.
