About this map

High-altitude mining history and the early footprint of the outdoor recreation industry converge in this 1958 survey of the Summit County mountains. Silver and lead mining remnants are scattered across the high peaks, particularly around Glacier Mountain and the settlement of Saints John. Named mines like the Wild Irishman Mine and Saints John Mine mark the steep slopes above Saints John Creek, while the Hunkidori Mine sits deep within Grizzly Gulch.

The landscape's mid-century transition is visible through the early development of the Keystone Ski Area near the village of Keystone, and the extensive infrastructure of the Roberts Diversion Tunnel cutting through the mountains. To the south, the dredging and mining legacy of the Swan River is documented by significant Tailings deposits and the remote settlement of Swandyke. The map illustrates a rugged geography defined by the Continental Divide's drainage systems, including the North Fork Snake River and its various tributary gulches.
