About this map

Iron Mtn rises above the basin floor in this high desert region of Harney County, serving as a primary landmark for the surrounding Iron Mountain Flat. The landscape is defined by its seasonal water features and volcanic landforms, including the depressions of Hughet Lake and Silver Lake to the north. These ephemeral basins, along with sites like Lakebed Waterhole and Pool Spring, indicate the historical importance of water management in this arid environment.

Evidence of geological erosion is visible through the drainage of Buzzard Cr and the etched walls of Buzzard Canyon and Black Canyon. Human activity is primarily represented by the remote track of Big Stick Rd, which traverses the flat, connecting the various springs and potholes such as Angie Potholes. This survey by the U.S. Geological Survey details a transition zone between the elevated Coyote Rim and the lower reaches of Warm Springs Valley.
