Description
Preliminary Interpretive Report PIR 2001-3B, Bedrock geologic map of the Eagle A-2 Quadrangle, Fortymile mining district, provides 1:63,360-scale geologic mapping of the Eagle A-2 Quadrangle (270 square miles; equivalent to four 7.5-minute quadrangles). The area is part of the 100-year old Fortymile mining district located in eastern Alaska near the Alaska-Yukon border. This geologic map was produced based upon results from field investigations by DGGS in 1999 and 2000, which were part of a three-year mapping program to provide geologic ground truth for airborne geophysical surveys flown by DGGS in the Fortymile mining district during 1998. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: http://doi.org/10.14509/2670.
