2021 Map of Cordero Mine

About this map

The borderlands between Humboldt County, Nevada, and Malheur County, Oregon, are defined by an arid basin landscape where the northern edge of the Quinn River Valley meets the high desert plateaus. At the heart of this 2021 survey sits the mining community of Cordero, situated along State Hwy 793. The map details the transition from the relatively flat valley floor, drained by the Quinn River and McDermitt Cr, to the more complex topography of the south, where Long Canyon and McConnell Canyon cut through the rising terrain. Transportation in this high-desert environment relies on a network of functional routes including Cordero Rd and Co Line Rd, reflecting the area's ongoing industrial and mining significance near the state line.
