This bedrock geologic map was produced by using airborne magnetic and electromagnetic surveys, data and notes from several months of fieldwork, geochemical data, and laboratory investigations. These maps are the result of new field investigations in the Eagle A-1 Quadrangle by DGGS in 1999, 2000, and 2001. Field investigations are 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.

This geologic map was produced by merging a bedrock geologic map and a surficial geologic map of the Eagle A-1 Quadrangle. Surficial geologic units were determined by a combination of air photo interpretation and site-specific field investigations. Bedrock geologic units were determined by using a combination of airborne magnetic and electromagnetic surveys, several months of fieldwork, geochemical data, and laboratory investigations. These maps are the result of new field investigations by DGGS in 1999 and 2001.

Report of Investigation 2006-2, "Bedrock geologic map of the Liberty Bell area, Fairbanks A-4 Quadrangle, Bonnifield mining district, Alaska," is the bedrock geologic map of an approximately 131-square-mile area surrounding the Liberty Bell Mine. The geology of the Liberty Bell area, located in the northern Alaska Range foothills, comprises Devonian metasedimentary and meta-igneous rocks of the Totatlanika Schist and Keevy Peak formations, Cretaceous and Tertiary igneous rocks, and overlying unconsolidated Tertiary sedimentary rocks of the Usibelli Group and the younger Nenana Gravel.
