This is a 1956 Santiago Hernandez Sanchez Mejorada geological map of western Mexico including most of Sonora. The map depicts Mexico from the Pacific Ocean to Zacatecas and Coahuila and from the U.S.-Mexico border to Jalisco and Michoacán. Twenty-five different geological formations are identified in the key in the lower left corner, ranging from Pre-Cambrian to Pleistocene. The colors are vibrant and are easily identified, particularly the shade of red on Baja California and the blues which are scattered throughout the map. This eye-catching piece apperas to be the western part of a larger 2 sheet set.

This map was compiled by Santiago Hernandez Sanchez Mejorada in 1956.
