Report of reconnaissance of the Albuquerque NTMS quadrangle through water and sediment samples collected from springs, wells, and streams. Samples analyzed for uranium and 42 other elements. This report is limited to samples containing uranium concentrations greater than the arbitrary anomaly thresholds of 5 parts per billion for waters and 6 parts per million for sediments.

Preface: This report contains data and information on the resurvey effort and the effect of residual contamination as a result of nuclear weapons development programs conducted in this area.

From introduction: This report describes the results of water and sediment sampling within the New Mexico portions (or western halves) of the Hobbs'and Brownfield, New Mexico/Texas, National Topographic Map Series (NTMS) 1:250 000-scale quadrangles.

From introduction: This report describes work done in the Tularosa, New Mexico, National Topographic Map Series (NTMS) quadrangle (1:250 000 scale) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).

From introduction: This final report .is organized in two logical sections: (a) Volume I, containing the survey description, specifications, data processing methods, interpretation methods, regional geologic review and regional survey results and (b) one volume, Volume II, for each of the three quadrangles covered by the Raton Basin Project Area. Each Volume II contains a detailed geologic summary, interpretation report, standard deviation maps, pseudo-contour maps, interpretation map, flight line and geologic base map, individual corrected profiles, computer map unit histograms and statistical tables.

Appendix containing tables to accompany a report on an aerial gamma ray and magnetic survey in the Raton Basin in Arizona and New Mexico.

Second volume of a report documenting a high-sensitivity airborne radiometric and magnetic survey of the Gallup quadrangle including results of data interpretation, significance factor profile maps, stacked profiles, and histograms.

Second volume of a report documenting a high-sensitivity airborne radiometric and magnetic survey of the Shiprock quadrangle including results of data interpretation, significance factor profile maps, stacked profiles, and histograms.

"Eight high-explosive charges weighing 8 to 1000 pounds were detonated in playa. Each event included 24 to 40 locations of tracer material in the expected crater region. The objective was to obtain data relating the origin of crater ejecta to its depositional location. Resulting data are presented for craters, ejecta areal densities, crater and ejecta mass quantities, tracer dispersion, and an empirical prediction model."
