Introduction

The California State Geological Survey was begun, in effect, on February 2, 1860, when Senator Logan introduced a bill for "an Act to create the Office of State Geologist and define the duties thereof." (Senate Journal, 1860, page 243.) This bill was passed on April 13 of the same year, and was later amended slightly. Professor J. D. Whitney was appointed State Geologist, and on February 27, 1862, addressed the Legislature concerning the study of geology, and stressed the need for a Geological Survey of California. (Appendix to the Journals of the Senate and Assembly, 1862.) The Survey itself was apparently begun early in 1863, and a "Letter of, the State Geologist relative to the progress of the State Geological Survey during the years 1863-1864" was issued by Whitney in 1866. Annual reports stating further progress were issued annually through 1872-1873. In 1874, a Joint Committee on the Geological Survey, in its report to the Governor, recommended the continuation of the Survey, and appended a statement by Whitney which also asked that the Survey be allowed to complete its work. (Appendix to the Journals of the Senate and Assembly, vol. 5, 1874.)
In spite of these recommendations, however, work on the Survey was apparently stopped in 1874, and its records and property were turned over to the University of California. According to John P. Ryan, who made an inventory of the remaining Papers at the time that they were given to Bancroft Library in October of 1952, "in the Annual Report of the University Secretary... for the year ending June 30, 1890, there is given a complete list of the books, maps and plates that were stored in the Library 12/23/89. In 1925 the Legislature authorized the University to dispose of this material in any way they saw fit. At a later date a trunk containing some of the maps was turned over to the Geology Department. In October 1952 this latter material was given to the Bancroft Library. The balance of the material has not been discovered. Inquiries have been made at the Geology, Palaeontology, Botany, Geography and Mining Departments of the University. The material in the basement of the Women's Building and on the 7 floors of the Bell Tower has been examined without results."
A list of the papers and property of the Survey is also given at the end of the Report of the Joint Committee mentioned above. In addition to the materials published in the Journals of the Senate and Assembly and their appendices, an article concerning the progress of the Survey was published in the American Journal of Science and Arts, vol. XXXVIII, no. 113, September 1964 (cataloged in Bancroft Library as F 870 S2 W5.)

California Geological Survey Maps

Note

For descriptions of individual maps see online catalog call number G9990.C3 no.

Scope and Content Note

The maps in this collection are, for the most part, preliminary sketches for the printed maps published by the California State Geological Survey between 1867 and 1874. However, since their scale is generally larger, their detail is greater, and they may include information not transferred to the printed maps.
The largest single group of maps concerns Nevada and Placer Counties. About half of these are plots of mining claims, and the other half relate to Bowman's report on Auriferous gravels, Papers no. 2; these last are identified by their reference to "Pliocene gravels." Except for three maps, the collection is restricted to California and Nevada. The three exceptions concern, respectively, the Oregon border, Colorado, and central Europe.
The numbers identifying the maps in the following list correspond to no system of arrangement, but refer simply to the order in which the maps are filed. For a table showing the correlation between these numbers and those assigned when the maps were originally turned over to the University, see the last section of this guide.
Maps of a single specific location, i. e. Grass Valley, Mono County, La Purissima Mission, etc., are listed fully under that name. When necessary - particularly in the case of the names of mining claims - there are one or more cross references either under the name of the county in which the place lies or of the city which it is near. When a map includes the area of more than one, but less than four, counties, it is listed fully under each county concerned; when four or more counties are involved, it is listed under the particular area of the state concerned, i. e. California (North-central), etc.
