Established in 1874 as an agricultural lifeline, La Plata County, Colorado, has played many roles. European Americans were drawn to the region by the promise of mineral wealth and the mining industry. Agriculture, smelting, transportation, and commerce grew to offer support. As the county matured, its Old West features were discovered, and it was dubbed "Hollywood of the Rockies" when movies were filmed there from the 1940s to the 1960s with notable stars such as Clark Gable, Jimmy Stewart, Marilyn Monroe, Paul Newman, and Robert Redford. The 20th century brought energy extraction and commercial growth, but as the recreational opportunities in the region started to be discovered, La Plata County became a destination for outdoor pursuits. The county has 14,000-foot peaks, rivers, and hundreds of miles of hiking, biking, and ski trails. Today, tourism and recreation drive the economy much as the mining industry once did. Within these pages, historical photographs from the archives of the La Plata County Historical Society illustrate the many facets of this Colorado county. Edward Anthony Horvat is a third-generation La Plata County native; his grandparents all came to the county between 1905 and 1911. A retired nurse-paramedic, Horvat volunteers at the historical society's Animas Museum and writes the weekly And the West Is History feature in the Durango Herald newspaper.
