Aeromagnetic and interpretation map of the King Range and Chemise Mountain Instant Study Areas, Northern California

The data for the aeromagnetic map (sheet 1) of the King Range and Chemise Mountain areas wre collected in 1978 and compiled at a scale of 1:62,500. Northeast-southwest traverses were spaced at 0.8-km intervals at an altitude for 300 m above the ground surface and 600 m above the ocean because of cliffs along the shore. The contour interval is 10 of or 50γ, depending on the steepness of local gradients in the Earth's magnetic field. A regional field of approximately 5.6 γ/km was removed from the data before contouring.
