About this map

Sumpter serves as the focal point of this Eastern Oregon survey, capturing the region during a period of significant mining and railroad expansion. The narrow-gauge Sumpter Valley River R. R. winds through the topography, connecting timber and mineral interests between the Blue Mountains and the Powder River valley. This transportation network was critical for operations like the French Diggings and the Redboy and Baisley-Elkhorn mines, which were established deep in the high-elevation terrain of Elkhorn Ridge.

Highland settlements and camps such as Bourne, Greenhorn, and Geiser illustrate the era's scattered mountain economy. The map traces the headwaters of the North Fork John Day River and shows a landscape dotted with alpine features like Anthony Lakes and Killamacue Lake. These details offer a clear view of the complex relationship between early industrial extraction and the natural drainage systems of the Blue Mountains.
