A., 1999, Preliminary digital map of cryptocrystalline occurrences in northern Nevada:U.S. Geological Survey Open-File Report 99-523, 38p. Description: Abstract: A polygon Arcview shapefile of northern Nevada cryptocrystalline occurrences derived from Nevada rockhound guides and converted to a coverage. Purpose: The polygon shapefile was combined with a point shapefile derived from the U.S. Geological Survey's Mineral Resources Data System (MRDS) to create a preliminary digital map of cryptocrystalline occurrences of northern Nevada. The original intent was to identify potential sources of raw materials for tools used by indigenous people of northern Nevada. The dataset was created to assist government agencies and others in making resource management decisions using geographic information systems (GIS). Uses of the spatial data set include, but are not limited to, natural and cultural resource management, interdisciplinary activities, recreational rockhounding, and gold exploration. Supplemental_Information: The primary focus was potential raw material sites for tools made by native northern Nevadans. Archaeologists routinely rely on pottery and projectile points for dating techniques. Since basketry was more appropriate for the nomadic lifestyle of the native northern Nevadans, the major dating device for the Great Basin archaeological sites has been the projectile point. Preliminary investigation of the types of raw materials used for tool making by indigenous people of Northern Nevada led to decisions regarding the kind of occurrences considered to be cryptocrystalline for this spatial data set. The rockhound sites were descriptive and not based in a coordinate system. The ArcView distance-measuring tool was used to locate the sites in creating the ArcView 3.0 polygon theme, rkhnd.shp. Eighty-two cryptocrystalline sites were spatially referenced using Nevada 1:100,000 scale digital raster graphic (DRG) maps in UTM projection as background images (Nevada Bureau of Mines and Geology, 1996). Sites were located by measuring described distances and directions along roads and marking with polygon shapes. The size of the polygon represents the distributed or scattered area of the cryptocrystalline material, not the amount of material. The smooth, symmetrical (rather than irregular) shape of the polygon reflects the lack of point-to-point accuracy resulting from the location descriptions. A REFERENCE field numerically codes location accuracy in the polygon theme table, rkhnd.dbf. The polygon TYPE field categorizes the cryptocrystalline material for each rockhound site, and attribute color-coding corresponds to the TYPE field in the point theme table. A MRDS point theme and rockhound polygon theme were combined with an ARC/INFO coverage of Nevada county boundaries and an ArcView 3.0 layout was designed at 1:750,000 scale in UTM Zone 11 map projection. An additional ARC/INFO coverage of northern Nevada roads was used to create the digital preliminary map of northern Nevada cryptocrystalline occurrences.

For some purposes a field check may be advisable. All attributes created were verified by display in the spatial database, but no formal tests were performed. Logical_Consistency_Report: These data are believed to be logically consistent, although no formal tests were performed. Completeness_Report: The area of interest was within the northern Nevada state boundary and bounded in the south by 39 degrees north lattitude. The cryptocrystalline materials considered were chalcedony, chert, jasper, opal, obsidian, and cutting materials. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: No tests or field checks were performed, and accuracy varies according to description accuracy in the rockhound guides. Polygon size represents the distribution not quantity of the crytocrystalline material. The smooth polygon shape reflects the lack of point to point accuracy resulting from the location descriptions.
