About this map

Mining operations and timber-fed narrow gauge rail lines dominate this late-nineteenth-century landscape within the Blue Mountains. The thriving hub of Sumpter sits at the head of the Sumpter Valley River, serving as a vital nexus for the region's intense gold mining activity. High in the Elkhorn Ridge, specialized lode mines such as the Baisley-Elkhorn, Columbia, and Golconda are clearly marked, illustrating the shift from early placer mining to industrial quartz operations. This survey captures several small settlements and camps including Belleview, Bourne, and Robinsonville during the peak of the Eastern Oregon mining boom.

Water management is essential to the local economy, evidenced by the extensive Auburn Ditch cutting across the mountain slopes to support hydraulic operations. The terrain is marked by high-altitude features like Rock Creek Butte and Bald Mt., while the southern reaches descend toward the Middle Fork Burnt River. The proximity of the Union Grant and various county lines underscores the complex jurisdictional boundaries of this resource-rich territory at the turn of the century.
