2018 Map of Denio

About this map

The high desert of the Great Basin meets the Oregon border at Denio Junction, a remote crossroads where the Pueblo Mountains and the Pine Forest Range converge. This 2018 survey documents a landscape defined by scarce water resources and wide-open basins, including Bog Hot Valley and the seasonal expanse of Continental Lake. Geothermal activity is evident at Baltazor Hot Spring, while numerous named seeps such as Mustang Spring and State Line Spring reveal the vital hydrology supporting this arid region. The map also traces the historical movement of people through Emigrant Pass and the development of local infrastructure like the Denio Junction Airport. From the cattle-ranching legacy in Alberson Basin to the steep terrain of Black Mtn, the sheet provides a precise record of this tri-county borderland where Nevada and Oregon meet.
