Ochocco National Forest dominates this 1990 provisional study, revealing a high-elevation landscape defined by its remote water sources and complex county boundaries. The map centers on the tri-county junction of Crook, Grant, and Harney counties, a point situated amidst the headwaters of several drainages including Silver Creek and Twelvemile Creek. The hydrology of the area is particularly detailed, showing both natural features like Delintment Lake and man-made infrastructure such as Grindstone Reservoir and Williams Reservoir.
