About the NTS_UGE Database: The NTS_UGE database was compiled from data collected by the DOE Nevada Operations, Lawrence Livermore National Laboratory, Los Alamos National Laboratory, and the USGS Water Resource Division. The purpose of the NTS_UGE database was "to establish accurate and well-know source information on nuclear tests including event (detonation) names, borehole names, locations, working points, land surface elevations, and regional water level estimates so that cross references to other existing databases that are used in the management of nuclear event data could be made; and to determine, based on various criteria, the events that most likely were detonated in close proximity to the regional ground water system." The NTS_UGE database was intended to be the standard database on underground nuclear tests at the NTS, and to be used by DOE/NV Environmental Restoration Division.

The tedious task of mapping surface effects at the Nevada Test Site was originally conducted by many investigators of the U.S. Geological Survey, the Los Alamos National Laboratory, the Lawrence Livermore National Laboratory, and the Defense Threat Reduction Agency. These investigators comprehensively documented the surface effects of more than two-thirds of all underground nuclear detonations conducted at Yucca Flat and all of the detonations conducted at Pahute Mesa. A short list of those involved include F.M. Byers Jr., H.R. Covington, D.D. Dickey, G.L. Dixon, M.N. Garcia, E.C. Jenkins, Florian Maldonado, P.P. Orkild, T.L. Prather, R.P. Snyder, R.R. Spengler, Susan Steele Wier, Pete Thompson, W.S. Twenhofel, and Dean Townsend of the USGS; and Brian Allen, Anne Cavazos, Sigmund Drellack, Jose Gonzales, Ward Hawkins, Richard McArthur, Lawrence McKague, William McKinnis, Lance Prothro, William Davies, Casey Schmidt, and Margaret Townsend of the National Laboratories. Their combined mapping efforts and reports documented the surface effects produced by nearly 41 years of underground nuclear detonations at the Nevada Test Site between 1951 and 1992. The digital GIS data presented here will preserve the arduous achievements of those who spent countless hours in the pursuit of knowledge and understanding about the surface effects of underground nuclear testing at the Nevada Test Site.

The surface effects sites database is used to identify and display the locations of all underground detonations at the NTS. The database contains information related to each detonation, as well as information about the surface effects maps that were produced for the detonations. The database can be used to query and select detonations and boreholes based on the fields "Name" or "Siteid," and to select and map specific detonations or groups of detonations based on user-specified surface effects characteristics.

All attribute data were entered during the digitizing process. Each digitized map contains a logical array of attributes. Each detonation listed in the sites detonation database contains attributes pertinent to the detonation and surface effects maps. Information about these attributes is listed in this metadata file. The attributes were verified against the original source maps, and thoroughly tested for accuracy, naming consistency, and spelling.
The horizontal positional accuracy of each detonation site was numerically verified against site locations contained in the master sites database maintained by DOE/NV and compared to the detonation site locations shown on the original mylar surface effects maps. Nevada State Plane Coordinates (Eastings and Northings) were used for the detonation site (point) locations and to compute the UTM coordinate pairs contained in the database.
Vertical data contained in the sites database were derived from the NTS_UGE database. No formal testing was conducted to verify the accruacy of these data.
These data are complete. All available surface effects maps were scanned, georeferenced, and digitally reproduced. These maps comprise the GIS surface effects map archive for the Nevada Test Site. Any maps that were lost, misplaced, or destroyed prior to the start of this project in 1998 were unavailable, and therefore not included in the archive.
The data contained in the sites database were derived from the NTS_UGE database and from the "original" surface effects maps. The NTS_UGE database was intended to be the standard database on underground nuclear tests at the NTS, and to be used by the DOE/NV Environmental Restoration Division. The "original" surface effects maps document all observed and identified surface effects directly on aerial photographs or topographic base maps at scales ranging from 1:1,200 to 1:2,400. Some of these surface effects maps were published in USGS Open-File Reports and Professional Papers, however, most were stored as unpublished maps, reports, and memos, and some were only stored as raw field notes. For each site, every attempt was made to find the "final" version of the map (preferably the master drawing for clarity) and to verify map scale and authenticity. Information derived from these "original" maps is included in this database.
