1971 Map of Silver Lake

About this map

Cable Mountain dominates the high-altitude industrial landscape of the Deerlodge National Forest in this 1971 record. The map details a complex network of resource extraction and infrastructure, centered around the historic Southern Cross and Georgetown settlements. Significant mining operations are documented across the slopes, including the prominent Cable Mine, Gold Coin Mine, and Trigger Mine. The management of water for downstream use is evident through the large Aqueduct and Flume systems connected to Silver Lake, which features a dedicated Pumping Sta. Beyond industry, the sheet captures the recreational and social footprint of the era, from the Anaconda Civilian Conservation Center to several mountain campgrounds and the Cable Lookout Tower perched atop the ridge. An Old Railroad Grade winding toward Yankee Flat Creek suggests the evolving transportation patterns of this mountain corridor.
