2024 Map of Bourne

About this map

Sumpter and the smaller settlement of Bourne occupy a high-elevation landscape defined by the drainages of Cracker Creek and the McCully Fork. This modern survey reveals a complex network of recreational paths, including the Sumpter Loop Snowmobile Trail and the high-elevation Elkhorn Crest Trail that traverses Elkhorn Ridge. The area is characterized by steep glacial topography and resource management within the Whitman National Forest, with significant water features like the Sumpter Reservoir and alpine bodies such as Killamacue Lake. The map details the transition between the mining-era settlements in the valley floors and the protected heights of the North Fork John Day Wilderness. Prominent landmarks like Wind Creek Peak and the rugged Chloride Ridge dominate the northern skyline, while the historic boundary between Grant and Baker counties cuts through the northwest corner near the North Fork John Day River.
