High-Resolution Aeromagnetic Survey of the Wenatchee Area, Washington

April 13, 2020

This data release provides access to a low-altitude, aeromagnetic survey of a part of central Washington, an area that includes the city of Wenatchee and the towns of Entiat, Chelan, and Leavenworth. The Wenatchee aeromagnetic survey extends westward from the Columbia Plateau to the Cascade Range, and covers a part of the Columbia River and Lake Chelan. The survey was conducted between October 17 and December 5, 2011, by Firefly Aviation Ltd., working under contract to the U.S. Geological Survey. Total magnetic field values were acquired using a fixed-wing aircraft flown at a target elevation of 150 m above terrain and along flight lines and tie lines spaced 400 m and 4000 m apart, respectively. Flight lines were directed east-west, and tie lines were directed north-south. A total of 24,000 line-kilometers were acquired. The details of the Wenatchee aeromagnetic survey are described in the document, Wenatche_Tech_Report.pdf available for download in this data release.
