Prospecting For Gold in Southern California in the 1950s
The "Placer Map of California (South Half)" created by Walter J. Robertson provides a detailed guide to known gold placer deposits and uranium prospect sites across Southern California. Designed for prospectors and hobbyists, the map highlights potential gold areas represented by shaded dots and uranium prospects marked as "UR." This map covers key regions, including Inyo, Kern, San Bernardino, Los Angeles, Orange, Ventura, and Imperial Counties, where each numbered site corresponds to a description that details specific placer sites.
The descriptions alongside the map offer insight into the types of deposits and accessibility of each site. For example, Mazourka Canyon in Inyo County is noted as a challenging location, recommended only for experienced prospectors, while the Kern River placers are described as more accessible, with specifics on the surrounding topography. Some regions, like Holcomb Valley in San Bernardino County, are listed for their historical placer sites, providing a rich context for seasoned and new prospectors alike.
In addition to detailing gold and uranium sites, the map offers practical advice for prospective miners. Robertson suggests using a standard road map alongside this placer map for better navigation and provides reminders on essentials such as carrying extra water, checking local conditions before setting out, and respecting private property. This guidance aims to prepare prospectors for the remote and often rugged terrain of California’s southern gold and uranium fields.
Advertisements for prospecting literature are also included, promoting Robertson’s additional resources. Titles such as "Prospecting for Gold" and "Let’s Go Prospecting," both offered at $3.00, promise more detailed maps and insights into prospecting techniques, aiming to equip readers with further knowledge on where to search for valuable minerals.
