About this map

Silver Eagle Shaft and the North Silver King Mine anchor this high-elevation landscape within the Toiyabe National Forest, documenting the intense subterranean exploration of the late 1960s. The map reveals a dense network of mining infrastructure focused on the canyons, including the Chase Tunnel, True Blue Tunnel, and the Morris and Caple Tunnel. These features, clustered around San Francisco Canyon and New York Canyon, illustrate the persistent search for minerals in the Great Basin.

Evidence of the region's overland history appears at Emigrant Pass, where a jeep trail follows the path of Emigrant Canyon. Water sources were critical for both mining operations and travelers, evidenced by the distribution of Rose Bud Springs, Cold Spring, and the Upper Midas Spring. A remote Landing Strip and a Substation in the lower valleys indicate the modern industrial support required to maintain these isolated outposts.
