Aeromagnetic map of the Tanacross Quadrangle, Alaska
Andrew Griscom
1976, Miscellaneous Field Studies Map 767-A
The aeromagnetic map (sheet 1) of the Tanacross quadrangle was prepared in 1971 and subsequently released by the State of Alaska as an open-file map (Alaska Div. Geology and Geophysics, 1973). The data were collected along north-south traverses spaced at 1.6-km intervals and from an altitude of 300 m above...

G.C. Curtin, G.W. Day, R. M. O’Leary, S.P. Marsh, R. B. Tripp
1976, Miscellaneous Field Studies Map 767-M
This geochemical map delineates drainage basins in which either anomalous copper, molybdenum, or both copper and molybdenum were detected in at least one of four sample media: (A) the oxide residue (the oxalic-acid-leachable fraction) of the stream sediment, (B) the minus-80-mesh stream sediment, (C) the ash of streambank sod (mixed...
