The Association of American State Geologists (AASG) represents the State Geologists of the States and Puerto Rico. Founded in 1908, AASG advances the science and practical application of geology and related earth sciences in the United States and its territories, commonwealths, and possessions.

In the context of continuing unjust treatment toward members of our society, AASG is taking steps to ensure that we will more actively face injustices and commit to challenging and changing the biases that lead to discriminatory practices. Read AASG's Diversity, Equity, and Inclusion (DEI) statement here.
