Mission Statement


The Mount Diablo Surveyors Historical Society was created by a group of California surveyors in 1989 that work in the United States Public Land Survey System and subsequent subdivisions thereof, is influenced and referenced to the Mount Diablo Meridian for the public land surveys of a large portion of California and all of Nevada.


The Society is a California non-profit public benefit corporation organized in 1990 under IRS 501 (c) 3, (Federal #89168065802, California #1835904). Our members are located throughout California and Nevada with additional members located nationwide. The membership is comprised primarily of Professional Land Surveyors and non-professionals alike. No requirements are placed on membership; all interested persons are encouraged to join.


The Mount Diablo Surveyors Historical Society is committed to preserving the instruments, artifacts and records used and created by the surveyors who worked in and around the area under the influence of the Mount Diablo Meridian. To this end, the society is accumulating instruments, records, photographs, maps and documents, which represent this endeavor. The society also has published an educational hand out pamphlet entitled “Land Surveying, The Mt. Diablo Initial Point, its History and Use“ which is provided to Mt. Diablo State Park at no charge.


Other efforts of the Society include displays at surveyor’s conferences, Public service projects, special events at local parks and museums, and displays in public buildings

            “Collect, Preserve, and Display Artifacts of the Land Surveying Profession”
