communities of Howardsville, Eureka, and Silverton. Silverton was founded by mining entrepreneurs William Kearnes, Dempsey Reese, and Thomas Blair in 1874. The region boomed after George Howard and R. J. McNutt discovered the Sunnyside silver vein along Hurricane Peak. Gold was then discovered in 1882, which helped the region weather the Panic of 1893 far better than other mining communities, such as Aspen or Creede. The Sunnyside Mine would become one of Colorado's longest running and most productive mines. The mine was shut down after the 1929 stock market crash, but was acquired by Standard Metals Corp. in 1959, and reopened, finding gold in 1973 with the Little Mary vein. The region's economy was dealt a devastating blow in 1992 when the mine and the corresponding Shenandoah-Dives mill, the last operating in the region, permanently closed. The closure meant the end of jobs for over one third of Silverton's workforce. Tourism era The town has a long history of tourism and efforts to market tourism by the Silverton Commercial Club (now the Chamber of Commerce) dates back as early as 1913. By the 1930s, interest in the “Old West” was already attracting tourists from around the world, for which the newly constructed U.S. Route 550 further enabled access. Following World War II, the town's railroad, originally operated by the Denver & Rio Grande Western for the purpose of shipping ore to Durango, became a major tourist attraction after it was featured in several popular western films. By the 1970s, with almost all mining operations in the region shuttered, the train was almost entirely operated for the purpose of tourism. Tourism continued to increase in the latter part of the 20th century, but Silverton's harsh winters and isolation made it a summer-only attraction. Following the closure of Sunnyside, Silverton lost much of its tax base as the town's population dwindled to just over 500, a quarter of its peak population one hundred years earlier. The town's population, buoyed by strong summer tourism and an emerging winter economy, has since recovered. The construction of the expert-level ski area Silverton Mountain in 2002 marked the beginning of Silverton's year-round tourism. Another ski area, the Purgatory Resort, is marketed as being within the Durango Metropolitan Area but is actually closer to Silverton than it is to Durango. Winter festivals such as Skijoring have brought crowds that rival those in the summer, and the potential
