The town of Ouray sits at the head of the Uncompahgre River valley, serving as a mountain hub during this 1901-1902 survey. The local economy and transport are defined by the Denver and Rio Grande R. R., which follows the river northward past settlements like Bachelor Switch, Portland, and Hot Springs toward Dallas. This era is marked by the complex relationship between mining-era infrastructure and the high-altitude terrain, where industrial rail lines terminate at the edge of the Uncompahgre National Forest.
