Thorleifson, Harvey2023-08-292023-08-292023https://hdl.handle.net/11299/256180The Geologic Mapping Forum in Minneapolis in 2018 and 2019 was attended by ~100 geologic 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 coronavirus pandemic, the 2020 Geologic Mapping Forum planned for April 7th to 9th, 2020, was not held. It therefore was decided that GMF Online would be held as meetings of about two hours duration on Thursdays at Noon Central, about once per month, from early autumn until spring, in 2020/2021, and again in 2021/2022, and in 2022/2023. The intended GMF audience is geologic map authors and program managers, and the focus again was on geology rather than funding or GIS. Optional abstracts for the 20-minute invited talks were requested, and are presented here.engeologymappingabstractsForummeetingsReport
