GMF Online

GMF in 2018 and 2019 was attended by ~100 geological map authors, program managers and allied professionals from geological surveys and associated agencies, who met to discuss the status and future of geological mapping in the USA. Due to the COVID-19 situation, the 2020 Geologic Mapping Forum was not to be held.

Now, exciting developments are happening in the world of geologic mapping! Societal needs are escalating, our capabilities are dramatically improving, and new funding is arriving. GMF Online therefore will be held as meetings of up to two hours duration on Thursdays at Noon Central, on October 8, November 5, & December 3, 2020, and January 28, February 25, March 25, & April 22, 2021.


Speakers are being invited. Talks will be recorded and made available unless speakers request otherwise. Depending on the number of abstracts, we might schedule regional meetings in the New Year. Speakers are asked to submit a 1 to 2-page abstract to ASAP. The abstract guidelines are available here. Last year’s abstracts are here.


For info, please contact Harvey Thorleifson at Minnesota Geological Survey.

See you online this winter!
