About this map

The confluence of the Blue River and the Snake River anchors this landscape during a period when Dillon and Frisco served as vital transportation hubs. The map depicts a sophisticated mountain rail network, with the Colorado and Southern and the Denver and Rio Grande Western railroads converging at Dickey, which also features the Dickey Ranger Sta. This pre-reservoir era shows the original valley floor settlements before the landscape was altered by water management projects.

Industrial activity is evident at the Boss Mine on the slopes of Keller Mtn, while the Gore Range and Tenmile Range define the high-altitude terrain. The passage over Vail Pass and Shrine Pass marks the early routes through the Holy Cross National Forest, connecting the mining and ranching interests of Summit and Eagle counties. Remote outposts like Curtin and Valdora illustrate the scattered nature of alpine settlement during the mid-1930s.
