When Olaf Jenkins was appointed State Mineralogist in 1947, he began publication of the Mineral Information Service which was designed to inform the public on the geology and mineral resources of California.
Intended for the public, these reports are readable and interesting. And being California, they talk about GOLD!
The Tertiary Channels & Gravels of the Sierra Nevada in California are famous not only for the sheer volume of gold recovered from them, but also the dramatic hydraulic and drift mining methods used to mine them. The history of gold mining in California would not be complete without a coverage of these gravels.
