Geologic Mapping Forum Online 2021-2022

GMF 2021-2022 will be held virtually. Meetings of up to 2 hours duration will be held Thursday at Noon Central on select days.


As you know, exciting developments in geological mapping are intensifying. Societal needs are escalating, our capabilities are improving, and even more funding is arriving. We—MGS in coordination with AASG and NCGMP—therefore are pleased to announce that Thursday, 2-hour, Noon Central, Geologic Mapping Forum Online sessions will take place in the same format as last year, on Sep 30, Oct 28, Dec 2, Jan 27, Feb 10Feb 24, Mar 24, and Apr 21.

The intended GMF audience is geological map authors and program managers, and the focus again will be on geology rather than funding or GIS, which are covered by other meetings.

Abstracts for the 20-minute invited talks will be requested, and discussion sessions will be added as needed. Talks will be recorded and made available unless speakers request otherwise.

We will plan an in-person meeting in the future when the pandemic allows. Separately, regional and topical workshops will be arranged, as needed, by NCGMP.
