| New data needs |
Rock geochemistry, detailed mapping, geophysics. |
| Geologic mapping and modeling needs |
No modern 1:24,000 scale mapping exists. |
| Geophysical survey and modeling needs |
Inadequate Rank 4 and 5 aeromagnetic and radiometric data; Rank 1 data would be useful. |
| Digital elevation data needs |
Lidar complete. |
