2024 Map of Iron Mountain Flat

About this map

Iron Mountain rises as a prominent landmark in this desert landscape of high-plateau basins and seasonal waterholes. The map documents a complex drainage and catchment system within the northern reaches of the Malheur National Wildlife Refuge, where features like the Lakebed Waterhole, Pool Spring, and Crane Spring provide critical water sources in a largely arid environment. To the north, Coyote Rim overlooks the expansive Warm Springs Valley, while the southern reaches are defined by the broad Iron Mountain Flat and the descent into Angie Canyon. The inclusion of Big Stick Rd and Glenns Hole suggests a landscape managed for both wildlife preservation and limited rangeland access, where ephemeral features like Silver Lake and Angie Potholes only appear during periods of significant runoff.
