Summary

This data release provides access to a low-altitude, aeromagnetic survey of a part of central Washington centered approximately 22 km west-southwest of Ellensburg. The survey includes the cities of Ellensburg, Cle Elum, and Yakima and is referred to as the Cle Elum aeromagnetic survey. The Cle Elum aeromagnetic survey extends from the Columbia Plateau westward to the eastern Cascade Range and illuminates magnetic anomalies associated with folds and faults of the Yakima folds, including the Umtanum Ridge, Saddle Mountains, and Frenchman Hills anticlines. These data were acquired during August and September, 2008, by Firefly Aviation, Ltd., working under contract to the U.S. Geological Survey. Total magnetic field values were acquired [...]

Purpose

These data were acquired to support earthquake hazard investigations and geologic mapping in central Washington. Specific geologic targets were various structures in the Yakima folds believed to have produced earthquakes in Quaternary and more recent time. An interpretation of these data is presented in Blakely, R.J., Sherrod, B.L., Weaver, C.S., Wells, R.E., Rohay, A.C., Barnett, E.A., and Knepprath, N.E., 2011, Connecting the Yakima fold and thrust belt to active faults in the Puget Lowland, Washington: Journal of Geophysical Research, v. 116, B07105, doi:10.1029/2010JB008091.
