Summary

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, [...]

Purpose

These data were acquired to support earthquake hazard investigations and geologic mapping in the greater Wenatchee area. The survey covers the presumed epicenter of the 1872 Chelan earthquake and ongoing seismic activity surrounding Entiat, Washington. Initial interpretation of these data is presented in Blakely, R.J., Sherrod, B.L., Wells, R.E., and Weaver, C.S., 2012, Peeking below Columbia River flood basalts with high-resolution aeromagnetic data: implications for central Washington earthquake hazards [abstract]: Abstract GP13C-02, presented at 2012 Fall Meeting, AGU, San Francisco, California, December 3-7, 2012.
