1980 Map of Iron Mtn. Flat

About this map

Iron Mountain rises as the dominant landmark in this high desert landscape of central Oregon, surveyed during the early 1970s. The map reveals an arid environment defined by seasonal water sources and expansive dry basins like Silver Lake and the vast Alkali Flat. Human activity in the region is marked primarily by sparse ranching infrastructure and land management, with numerous cattle-related water points such as Lakebed Waterhole and Dead Bull Waterhole scattered across the sagebrush-covered flats. The northeastern corner contains a portion of the Malheur Nat Wildlife Refuge, indicating the area's significance for migratory birds and conservation. A network of primitive transit routes, including the Stick Road and various jeep trails, provides access to isolated features like Hughet Lake and Glenns Hole, reflecting the remote and utilitarian nature of the Harney County interior during this era.
