| 11 | Fault. *** Note: arcs having the software-defined attribute/column FID whose values are "6 and 8" and "7 and 9" represent the Minook Creek and Victoria Creek Faults, respectively. The annotation "Minook Creek Fault" and "Victoria Creek Fault", as seen on the Derivative Map of Potential Geological Hazards in the Tanana B-1 Quadrangle, Central Alaska (Publication RI97-15E-SH1), is not preserved in the structure data. *** |

| 1 | Bounding box. *** Note: A code value of "1" is not correct. The correct code value for all software-defined attribute/column FIDs should be "6", which corresponds to a fault. *** |
| 2 | Contact. *** Note: A code value of "2" is not correct. The correct code value for all software-defined attribute/column FIDs should be "6", which corresponds to a fault. *** |
Funding for the geologic mapping and geochronologic dating performed for this project was provided by the U.S. Geological Survey STATEMAP Program under award number 1474-HQ-96-AG (June 1996 through May 1997) and by the Alaska State Legislature.

The Tanana B-1 quadrangle lies between the villages of Rampart, on the Yukon River, and Manley Hot Springs, at the terminus of the Elliot Highway. At the time this project was published the area towns were not part of any municipal or local governmental jurisdiction. The investigation of gold, tin, and other mineral occurrences in conjunction with comprehensive geologic mapping and recently acquired geophysical data will provide a scientific basis for continued mineral exploitation that will economically benefit the region's inhabitants and the State of Alaska. This publication also identifies sources of construction materials and evaluates the type and severity of geologic constraints to future development in the region.

Surficial and hazards point, line, and polygon data were determined in the field using 1:63,360-scale topographic maps and 1:50,000 (nominal) scale, color-infrared aerial photographs. Geologic data included in the compilation are the field maps and notes from this project as well as data from other sources as noted in the "Sources Cited" section. Attributes were verified for consistency and completeness during the creation of the metadata.
DGGS location data and estimated position errors were manually entered into a spreadsheet. Sample numbers and locations with selected data were spatially registered and analyzed in ArcGIS software. Location data for the surficial and materials maps were determined visually using topographic maps at a scale of 1:63,360 and 1:50,000 (nominal) scale, color-infrared aerial photographs. See "Source_Information" section for horizontal positional accuracy of locations not measured by DGGS.
This dataset includes geospatial information about geologic hazard units and structural features.
Polygon topology present and clean on appropriate data. Other data are line, point, or annotation data and do not require topologic relationships.
Are there legal restrictions on access or use of the data?
