New data needs Geophysics, geologic mapping.
Geologic mapping and modeling needs Current mapping inadequate.
Geophysical survey and modeling needs High resolution, Rank 1 aeromagnetic and aeroradiometric coverage and gravity survey needed.
Digital elevation data needs Lidar complete over approximately half of focus area; in progress (GeoDAWN) over remainder.
