About this map

The high desert landscape of central Oregon is defined here by the seasonal flow of the Crooked River and its South Fork, which meander through a series of marshes and irrigation ditches. Cattle ranching and water management dominate the human footprint in this part of Crook County, anchored by the prominent G I Ranch and the nearby Logan Reservoir. The map documents a sparsely populated region where early 1980s infrastructure consists primarily of unimproved roads and 4WD tracks connecting isolated points of interest.

Evidence of historical habitation and geography is preserved in labels for the Fife (Site) and the Scammon Place, suggesting the shifting nature of rural settlement in this arid environment. Significant topographical markers like Easterday Ridge, Rodman Rim, and Sears Canyon frame the valley, while features like Dry Lake and various waterholes underscore the critical importance of water rights and range management in this high-elevation terrain.
