Welcome to the Geologic Mapping Forum

At GMF, ~100 geological map authors, program managers, and allied professionals discuss on-going and future geological mapping in the US. We focus on geology, rather than funding or GIS which are better covered in other meetings. The US Congress and States have accelerated needed mapping, leading to important applications and exciting research. 

GMF is organized by UMN Professor Harvey Thorleifson, in association with NCGMP Coordinator Chris Swezey of USGS and AASG. In-person meetings were held in 2018 and 2019, and monthly winter online meetings have been held since the pandemic.

Here are past abstracts: 2018, 2019, 2020/2021, 2021/2022, 2022/2023, 2023/2024, 2024/2025, and 2025/2026; and the 2018 meeting summary. Videos for most online talks are available due to speaker consent. Resources are here.
