Map Of California Showing Generalized Classification Of Land With Regard To Oil Possibilities - Mapping California's Oil Boom In The Early 1920S. Lawrence Vander Leck

"This scarce lithographed map highlights the potential for oil production across the entire state of California, as of July 1921. White (proven), blue (possible), yellow (improbable), and pink (impossible) have been applied to various areas according to their likelihood of containing oil. Known fields include Midway-Sunset (Kern County), Los Angeles City (L.A. County), and Kern Front (Kern County). Around the time the map was published, California was the world's leading oil producer, supplying nearly 20% of global needs. Designed by Lawrence Vander Leck and printed by the California State Printing Office for the California State Mining Bureau in 1921. Issued as one of two plates with a corresponding report (not included). Scarce, with only two entries noted in OCLC at Cal State Fullerton and U.C. Santa Cruz.
