Map showing extent of glaciation in the Eagle quadrangle, east-central Alaska

This map covers the Eagle 1:250,000-scale quadrangle in the northeastern part of the Yukon-Tanana Upland in Alaska. It shows the extent of five major glacial advances, former glacial lakes, and present fragmented terrace deposits related to the advances.

Mesozoic magmatism and base-metal mineralization in the Fortymile mining district, eastern Alaska--Initial results of petrographic, geochemical, and isotopic studies in the Mount Veta area

Initial results of a petrographic, geochemical, and isotopic study of Mesozoic intrusive rocks and spatially associated Zn-Pb-Ag-Cu-Au prospects in the area.

Regional geochemical results from the reanalysis of NURE stream sediment samples--Eagle 3 degree quadrangle, east-central Alaska

Reanalyses of NURE sediment samples in the Fortymile mining district, east-central Alaska. Provides new lower limits for some elements. Compares data from newer analytical techniques with original NURE data.
