High-Resolution Aeromagnetic Survey Over Pendleton, Oregon, and Surrounding Areas
This data release provides access to a low-altitude, aeromagnetic survey over a part of northeastern Oregon, an area centered approximately over the city of La Grande. The survey is underlain by pre-Tertiary intrusive and metamorphic rocks exposed in the Wallowa Mountains and southern Blue Mountains, and basalts of the Miocene Columbia River Basalt Group exposed or shallowly buried elsewhere. The survey spans a part of the Klamath Mountains-Blue Mountains lineament, extending southwestward from the survey area to the Oregon Coast Range. These data were acquired between June 6 and August 3, 2017, by EDCON-PRJ, Inc., working under contract to the U.S. Geological Survey. The nominal flying height was based on a best fit, pre-planned, three-dimensional draped surface targeted at 200 m above terrain, subject to aircraft climb and descent limitations. Steep terrain in parts of the survey area required significant departures from the pre-planned drape surface, and therefore variable terrain clearance should be considered when modeling and interpreting these data. Flight lines were spaced 400 m apart and directed east-west; tie lines were spaced 4000 m apart and directed north-south. A total of 34,524 line-kilometers were acquired over an area of approximately 12,524 square kilometers. The details of the Pendleton aeromagnetic survey are described in the document Pendleton_Tech_Report.pdf available for download in this data release.
