NM Earth MRI Map
Map showing the location of the survey over New Mexico. The vast majority -- 90 % -- of aircraft flights will occur within the hatched area, while the remaining flights will be located in the northwestern portion of the project area. Flights will cover areas within the New Mexico counties of Doña Ana, Lincoln, Luna, Sierra, Socorro, Torrance, and Valenci
