Description

The Gold Placer Map of California – North Half, created by Walter J. Robertson of Stockton, California, provides a detailed representation of placer gold deposits across Northern California. The map identifies specific areas where placer gold—gold found in alluvial sediments such as rivers, streams, and creeks—has been historically discovered or mined. Designed for prospectors, it serves as both a practical guide and a historical artifact of gold mining in the region.

The map covers key counties in Northern California, including Del Norte, Trinity, Shasta, Sierra, and Placer, among others. It highlights rivers and tributaries such as the Feather, Yuba, Sacramento, and American Rivers, all of which were historically significant for gold mining, especially during the California Gold Rush. Accompanying notes at the bottom of the map provide detailed descriptions of gold-bearing regions, as well as specific streams and creeks where prospecting opportunities may still exist.

The explanatory text emphasizes that the map is intended to guide prospectors by outlining general and specific areas of interest but warns that not all areas are accessible or guaranteed to yield gold. The text includes practical tips, such as where to find placer gold deposits and the importance of staking claims before mining. Additional information lists nearby counties, rivers, and notable gold-producing sites, providing a comprehensive overview of the region’s placer gold potential.

This map reflects Northern California's rich history of gold mining, particularly during the Gold Rush era. It was likely created during a period of renewed interest in small-scale prospecting during the mid-20th century, offering hobbyists and miners a resource for exploring the region’s mineral wealth.
