Abstract
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 the ground. Compilation was originally in the form of 30 by 15-minute quadrangles at a scale of 1:63,500; these quadrangles have been combined and reduced to form the present map at a scale of 1:250,000. Contour interval is 10, 20, 100, or 500 gammas, depending upon the steepness of local gradients in the Earth's magnetic field.
