2021 Map of Unionville

About this map

Unionville sits at the foot of the Humboldt Range, where the mountains meet the expansive Buena Vista Valley. This area is defined by its deep canyons and historical transit corridors, most notably the Old Emigrant Rd which traces a path through the western foothills. The landscape is carved by seasonal drainages such as Coyote Cr and Cottonwood Cr, which descend from steep heights like Big Canyon and Buena Vista Canyon. Water remains a vital feature in this arid environment, marked by the presence of Harrison Spring on the valley floor. The road network, including the Bloody Canyon Rd and the Kyle Hot Springs Rd, illustrates the enduring connectivity between these isolated settlements and the surrounding basins, serving as a modern record of the region's ranching and mining heritage.
