Overall, the U.S. Geological Survey
(USGS) has a wealth of hard science and facts available online.
It can be a bit overwhelming. To help, you can visit www.usgs.gov/themes/
to see the USGS site organized along the Survey's
4 theme areas:
| Hazards | Natural Resources |
Environment |
|
Or, try the Survey's 4 administrative Divisions:
| Biology | Geology | Mapping | Water |
Also, the buttons to the left link to the portions of the USGS site structure relevant from a mining perspective.
