Unionville – Nevada was the original county seat for Humboldt County, serving in that capacity from its founding in July 1861 until the seat was relocated to Winnemucca in 1873. The big mining boom at Unionville occurred between 1863 and 1870. During that time, the population was reported to be as high as 1,500 persons. Mark Twain arrived in Unionville with the intention of prospecting for silver in 1862, describing the town as consisting of “eleven cabins and a liberty-pole”.
As is common in most mining communities, after the boom, the town experienced a decline soon afterwards. Today Unionville is the perfect place for your off the grid home. Currently, Unionville consists of a single business – a tourist inn – and a few small houses clustered along or near the gravel roadway which permits vehicular ingress and egress. The nearest paved road, an extension of this gravel road, is about 7 miles to the east. The nearest services of any sort, other than those available at the inn, are approximately one hour’s drive away.
