The Association of American State Geologists (AASG) represents the State Geologists of the 50 United States and Puerto Rico. Founded in 1908, AASG seeks to advance 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 the present national and international outcry over continuing unjust treatment toward people of color in this country, the Association of American State Geologists, during our annual meeting held the week of June 8th, 2020, took steps to ensure that we will more actively face injustices and commit to challenging and changing the biases that lead to discriminatory practices against people of color.
