About this collection

Olaf P. Jenkins, son of Stanford University professor Oliver P. Jenkins, earned his A.B, .M.A., and in 1930, his PhD. from Stanford University. He worked for state geological surveys in Tennessee, Washington, and Arizona and held positions with several private companies before he joined the California State Division of Mines in 1929. Serving as its chief from 1947 to 1958, he is credited with raising the division from a statistical mining bureau to one of the foremost state geological surveys of the nation. 

 

His lantern slide collection (1929 to 1933) covers the entirety of California and documents this shift of priorities.  With aerial and panoramic views of dynamic landforms and detailed photographs of formation geology, this collection is more about the forces of nature than the forces of man; how California’s geology was created, rather than exploited.

 

This collection also includes images of both geographically and geologically significant landmarks in the State including Yosemite and Lassen Peak.  Some of the photographs were subsequently published in the Annual Reports of the State Mineralogist. The lantern slides themselves measure 3.5 tall x 4 wide. As they could be projected onto a flat surface they were primarily used in conjunction with lectures and demonstrations.  The titles of the slides were supplied by Jenkins himself.
