Malheur National Forest dominates this landscape in Grant County, where the transition from high-desert valley to forested uplands is defined by a dense network of seasonal drainages and springs. The map documents the intricate terrain of the southern Ochoco Mountains region at the end of the 20th century, centered on the headwaters of Donaldson Creek and Cottonwood Creek. The presence of the Pismire Camp (Site) and a Gravel Pit indicates the historical land use patterns of resource extraction and seasonal habitation that have long characterized this part of Oregon.
