1969 Map of Bonanza King

About this map

Carrville and the surrounding river valleys define this 1969 revision of the Trinity Alps region, where the gold and mercury mining legacy of Northern California is clearly etched. Deep in the Shasta National Forest, the map details a landscape transition where the rising waters of Clair Engle Lake meet the historic drainage of the Trinity River. The survey identifies numerous industrial sites including the Bonanza King Mine and the Altoona Mine, alongside family holdings such as Eagle Creek Ranch and Trumble Ranch. High-altitude basins like Mumbo Basin and Tangle Blue Divide separate the watersheds of Coffee Creek and the North Fork Trinity River. The inclusion of the Whiskeytown-Shasta-Trinity National Recreation Area boundary reflects the shift toward mid-century conservation and recreation in a territory previously dominated by mineral extraction.
