About this map

Iron Mountain dominates the southwestern portion of this Harney County landscape, rising above the eponymous Iron Mountain Flat. This high desert environment is defined by its seasonal hydrology and volcanic topography, where the high point of Coyote Rim looks out over a complex system of ephemeral basins and catchments. The presence of Hughet Lake, Silver Lake, and the Lakebed Waterhole suggests a landscape shaped by intermittent water, critical for livestock and wildlife in the eastern Oregon interior.

Remote access is primarily maintained via the Big Stick Rd, which traverses the canyons and flats. Distinctive geological features like the Angie Potholes and Glenns Hole mark the terrain, while the descent into Buzzard Canyon and Angie Canyon provides significant relief. These named springs, including Crane Spring and Parr Spring, reveal the vital, localized water sources that historically dictated movement through the Warm Springs Valley.
