Thomas W. Dibblee Jr. Geological Foundation


The Dibblee Geological Foundation was created as a non-profit California education organization by those who admire the quality and quantity of Tom Dibblee's geologic mapping. The Foundation's mission is straightforward and simple: To help preserve the scientific, technical, educational and economic values of Dibblee's life work through timely publication. The Foundation consists of a group of volunteer directors and a staff of two, dedicated to publishing as many maps as possible.

Out immediate goal is to publish at least one hundred of Dibblee's most important geologic quadrangles. We recently passed the halfway mark, with a mosaic now of 83 maps (of 135 quadrangles), from Palos Verdes Peninsula to San Luis Obispo County! We print these maps in full color, with an attractive, consistent color scheme, and generally at a uniform scale (1:24,000), using USGS topographic base maps. The maps are available at low cost and contain only observable, understandable and reliable geological information of benefit to the broadest range of users.
