Donate to Support Geologic Maps Foundation. Mid-2025 Drive.

Thomas Davis is organizing this fundraiser to benefit Geologic Maps Foundation, Inc..

Tax deductible

We are raising money mid-year 2025 to benefit the Geologic Maps Foundation, Inc. (GMF). A donation will help make an impact on our geological mapping and educational efforts. GMF is an IRS designated 501 3c nonprofit and registered with the California State AG's office, https://oag.ca.gov/charities

GMF has now uploaded .pdf files of 257 geologic maps (mostly 7.5' quads, 1:24,000 scale) from southern and central California to the Geologic Maps Foundation, Inc. web page. Maps are free to download, https://geologicmapsfoundation.org/geologic-maps/

The original field mapping was done by Thomas W. Dibblee Jr. from the late 1930s to early 2000. Thomas L. Davis Geologist and staff digitized the original mapping in various GIS software over the last decade, and recently donated the .pdf copies to the Foundation. The .pdf maps are available for free at the Geologic Maps Foundation web page, https://geologicmapsfoundation.org/geologic-maps/

We have no employees (it's an all-volunteer effort). We occasionally hire GIS (Geographical Information Systems) experts and other map making consultants on a temporary basis to help us with our map preservation efforts.

Our educational efforts include Geo-hikes: Check out the Meetup link to see all the Geo-hikes we've run so far 2025 and in earlier years (click on the events tab and choose past or upcoming):
