In 1862, Dun Glen was established after silver was discovered in the area. The site was named for one of its early settlers, Angus Dun. By 1863, the mining camp became a commercial center with a population of 250. It was the second largest commercial district in northern Nevada. Early on it was variously called Dunn Glen or Dunglen. However its post office, opened on July 18, 1865 was called Dun Glen, and it operated as such until April 7, 1894. In 1863 the Sierra Mining district was formed 10 miles northeast of Mill City, with Dun Glen as its business center. In 1863 and 1865 to 1866, at the town's request, a small army garrison was stationed at
Camp Dun Glen within the town to protect the miners from Indians in the early part of the
Snake War. Dun Glen in the 1860s was one of the largest towns in northern Nevada. By the 1870s it had three
stamping mills, but by 1880 mining declined and the population also had declined to 50 persons, supported only by the local cattle ranching in the area. Chinese miners attempted drift mining of the gold laden placer gravels between 1880 and 1890 with limited success due to the water table. By 1894, Dun Glen was nearly deserted. ==Chafey==
