Map of Western Portion of Siskiyou County Showing Locations of Principal Gold Mines (1935)
This 1935 map, titled Map of Western Portion of Siskiyou County Showing Locations of Principal Gold Mines, was created to accompany a report on the mines and mineral resources of Siskiyou County by Charles V. Averill. Published by the State of California's Department of Natural Resources under the direction of George D. Nordenholt, this map provides a detailed representation of the gold mining activities in the western part of Siskiyou County, California.
The map meticulously marks the locations of over a hundred gold mines, both placer and lode types, with placers specifically noted by the designation "(P)" next to the mine names. It features a comprehensive index listing the mines numerically, allowing for easy cross-referencing between the map and the accompanying textual report. This indexing system highlights the extensive mining operations in the region, reflecting the significant role of gold mining in the county’s economic development during the early 20th century.
Geographically, the map is oriented with the north at the top and covers the area extending from the Oregon border in the north down to the boundary of Humboldt County in the south, and from the western ranges bordering the Pacific to the eastern edges approaching more inland terrains. The map is marked by a grid system of sections, townships, and ranges, typical of land surveys in the United States, facilitating precise location identification of mining claims and operations.
In addition to the mines, the map includes several notable geographic features such as rivers, creeks, and mountain peaks, which were integral to mining operations, particularly in facilitating the extraction and processing of gold. The cartography is characteristic of the period, with a clear and functional design intended for practical use by surveyors, miners, and other stakeholders in the mining industry.
This map serves not only as a practical guide to the locations of gold mines in Siskiyou County but also as a historical document that captures a snapshot of the mining landscape during the Great Depression era, a time when gold mining was a critical industry in California. It provides valuable insights into the distribution and scale of mining operations in one of the state's most mineral-rich regions.
