The Association of American State Geologists (AASG)
The Association of American State Geologists (AASG) is an organization of the chief executives of the state geological surveys and Puerto Rico. Nevada Bureau of Mines and Geology serves as the state geological survey for Nevada.
The responsibilities of the various state surveys differ from state to state, depending on the enabling legislation and the traditions under which the survey evolved. Almost all function as a basic information source for local, state, and federal agencies, mineral and energy industries, and basic and applied research.
The first state survey was established in 1823 in North Carolina. By 1840, there were at least 15 state surveys, most of which were charged with the discovery of mineral, energy, land, and water resources in their state or territory. The State Geologists began formal meetings with the U.S. Geological Survey in 1879, the year that organization was established. Since 1908, the Association has met regularly on an annual basis to discuss issues of common interest and to initiate united actions when warranted.
