A map showing our mapping progress

Geologic Maps Foundation (GMF) has uploaded .pdf files of 257 geologic maps (green on map image)

GMF has uploaded .pdf files of 257 geologic maps (mostly 7.5' quads, 1:24,000 scale and 15' quads, 1:62,500 scale) of southern and central California to the Geologic Maps Foundation, Inc.'s web page. Completed maps are shown in green-fill on the image below. Maps are high-resolution .pdf files and free to download. Eventually we hope to have the maps run on a smartphone with the ability to locate and track on the maps.

In addition, there is a mid-year 2025 fund raiser to benefit the Geologic Maps Foundation, Inc. (GMF). Donation link: https://gofund.me/800a6fdc
