About this map

Mining operations and remote ranching outposts define the high-altitude landscape of this mid-century survey. The settlement of Bonanza serves as a central point for a dense network of extraction sites, including the Bonanza Mine, Rawley Mine, and Eagle Mine. To the south, the Kerber City (Site) and various milling facilities like the Little Bonanza Mill indicate the area's industrial history.

Transportation through the mountains is marked by the Continental Divide and several key passes. An Old Grade Railroad snakes through the northeast corner past Mears Junction and Shirley, while the Marshall Pass and Poncha Pass provide critical routes through the peaks. Local genealogy is supported by the identification of several family-owned properties such as Blanchard Ranch, Shewalter Ranch, and Davidson Ranch, along with a small Cem located near the Bonanza townsite.
