The final Wyoming Territorial Legislative Assembly created Weston County in March 1890. Thirty years later, the discovery of oil at Osage, Wyo., halfway between the county seat of Newcastle and the small town of Upton, led to a number of cyclical economic booms and busts. Today, the county’s industries include agriculture and oil refining.

Upton, Wyo., known originally as Irontown or Iron City, and later as Merino, began in 1890 as a Burlington Railroad depot near a set of sheep corrals. The town was not incorporated until 1909. The Burlington’s successor, the BNSF, remains an important employer today, as do the school district and a clinic operated by Weston County Health Services.
