The geologic work was funded by the Alaska State Legislature through a Capital Improvement Project (Alaska Airborne Geophysical/Geological Mineral Inventory Program) and the general fund and through the U.S. Geological Survey STATEMAP program under U.S. Department of the Interior, U.S. Geological Survey, National Cooperative Geologic Mapping Program assistance award 01HQAG0054. The views and conclusions contained in this document are those of the authors and should not be interpreted as necessarily representing the official policies, either expressed or implied, of the U.S. Government. DGGS student interns and volunteers providing field assistance include Bryan A. Finseth (1999), Mark Mccrary (1999), J.C. Grady (2000), W.C. Munley (2000), and M.R. Johnson (2001). Milton A. Wiltse provided technical review of the maps. Jessica Mayer provided assistance with surficial geologic studies.
The purpose of the project was to produce a series of 1:63,360-scale geologic maps for a portion of the Fortymile mining district. The geologic data is important for characterizing and distinguishing between geologic units.Previously 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 greater detail is needed to identify critical geologic features that may relate to more regional geologic units. The Fortymile project is part of DGGS's Airborne Geophysical and Geological Mineral Inventory Program (AGGMI), a special multi-year investment by the State of Alaska to produce framework geologic maps that will expand the knowledge base of Alaska's geologic and mineral resources, catalyze future private-sector mineral exploration and development, and guide government agencies' planning.
