Preliminary Grid Data and Maps for an Aeromagnetic Survey of the Taylor Mountains Quadrangle and a Portion of the Bethel quadrangle, Alaska

A preliminary data grid and maps are presented for an aeromagnetic survey of
the Taylor Mountains and a portion of the Bethel quadrangles, Alaska. The
aeromagnetic survey was flown by McPhar Geosurveys Ltd. for the U.S. Geological
Survey (USGS). A flight-line spacing of 1,600 meters (1 mile) and nominal
flight height of 305 meters (1,000 feet) above topography (draped) was used for
the survey. The preliminary data grid has a grid cell size of 350 meters (1150
feet). Final data processing and quality control have not been applied to these
data. The purpose of this preliminary data release is to allow prompt public
access to these data, which are of interest for active mineral exploration in
the region. A more complete data release and description will be published
later once the final data processing is complete.
