From August 22 through August 25, 2011, the EPA Airborne Spectral Photometric Environmental Collection Technology (ASPECT) program conducted aerial surveys of nearly 22,000 acres of land near Ambrosia Lake, New Mexico. This area of New Mexico was extensively mined for uranium ore from the 1950s until the 1980s. The aerial survey was conducted to determine if residual contamination was present in areas exceeding natural background concentrations. In addition, nearly 375 aerial and oblique photographs were taken.
