2020 Map of Iron Mountain

About this map

Iron Mtn anchors the southern portion of this high desert landscape, which is defined by extensive volcanic features. The northern reaches of the quadrangle are dominated by the Saddle Butte Lava Field, a broad expanse of basaltic terrain that includes the Saddle Butte Lava Tube. This area of Malheur County shows minimal modern development, characterized primarily by the large-scale grid of the Public Land Survey System and a sparse network of unpaved desert routes like Kiger Rd and Tub Springs Rd. The topographical detail captures the complex drainage patterns and elevation changes across this volcanic plateau, illustrating how geology dictates the transit paths through the region. Land researchers can trace the intricate township and range boundaries that section the territory into distinct administrative blocks.
