Data for this survey were collected and processed by Sander Geophysics under contract with the USGS as part of the Earth Mapping Resources Initiative (Earth MRI) using a fixed wing aircraft with a magnetometer mounted in a tail stinger and a fully calibrated gamma ray spectrometer, data were collected along northwest-southeast flight lines spaced 250 meters (m) apart with northeast-southwest tie lines flown every 2500 m. The target terrain clearance was 100 m, with higher clearance over areas with rugged topography and population centers due to safety considerations.
