This project, resulting map, geospatial data are intended to provide a geologic map and a geologic interpretation of the Fortymile mining district at 1:63,360 scale. Previous published 1:63,360 scale geologic maps of this area have been reconnaissance-level maps or only covered portions of the quadrangle. Mapping at 1:63,360 scale (or more detailed) is needed to identify critical geologic features that may relate to more regional structures or geologic units. These detailed observations are also critical to test or use in tectonic models. This map also provides a geologic base in which to interpret geochemical results from the concurrent DGGS rock sampling program.

Data for original geologic units were digitized from a mylar and paper geologic compilations. This compilation for the surficial-geologic information was done on a paper map of the USGS topographic base for each of the 1:63,360 scale USGS topographic bases included in the map area. Bedrock geologic information was compiled on stable mylar with abundant control points at 1:50,000 scale that was scanned and co-registered in ArcView GIS Version 3.1? to a 1:63,360-scale USGS topographic base. 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. The derivative engineering-geologic data, was derived directly from the resulting comprehensive geology data.
Surficial mappers recorded observations on 1:50,000 scale (nominal) color-infrared aerial photographs and 1:63,360 scale topographic base maps.
This data set includes geospatial data about geologic units, pingo locations, geologic hazards, and potential construction materials resources.
Polygon topology present. Polygon topology present on appropriate data; others are line, point, or annotation data and do not require topologic relationships.
