About this map

The confluence of the Blue River, Snake River, and Tenmile Creek forms a central hub for transit and settlement in this 1929 survey. The town of Dillon sits at this junction, serving as a critical point on the Denver South Park and Pacific RR. This narrow-gauge line follows the river valleys, connecting smaller rail stops like Dickey and Frisco while navigating the significant verticality of the surrounding high country.

Evidence of the region's mining and administrative history is visible through the Boss Mine and the Dickey Ranger Sta. The map captures a landscape divided by the Gore Range and the Tenmile Range, where mountain passes like Shrine Pass and water sources such as Slate Lake and Willow Lakes dictated the movement of early travelers. Local history and genealogy researchers can trace original property placements and vanished locales like Delaware Flats and Braddocks before mid-century changes altered the valley floor.
