Using an ultra-light aircraft, a high-resolution aeromagnetic survey was carried out over Ormat Nevada's Glass Buttes project area in Oregon. Survey operations were completed on May 25, 2010. Average terrain clearance was 223 meters from the sensor. A total of 1,352 line-miles of aeromagnetic data were acquired. Processed survey data includes a total magnetic intensity map, reduced to pole (TMI) map, horizontal gradient (RTP) map, tilt derivative (RTP) map, and a horizontal gradient map of the tilt derivative grid.
