The total magnetic field corrected for the earth's ambient magnetization is shown in Fig. 2 (panel b). The Chena pluton and the two other metamorphic units stand out clearly with three different levels of magnetization values. A consistent anomaly of about 100-110 nT lies in the center of the panel in good agreement with location of the plutonic body on the geologic map (Fig. 2; panel d). There is an area of low magnetization centered on the resort location, which might be due to induced magnetization associated with man-made structures. This feature is useful as a visual representation of the resolution achieved during the airborne survey.
