Martha Sonntag Bradley writes about the history of Beaver County, Utah in the Utah Centennial County History Series.
"The settlement of Beaver County began in February 1856 when fifteen families from Parowan moved by wagon thirty miles north to Beaver Valley. The county was created by the Utah legislature on 31 January 1856, a week before the Parowan group set out to make their new home. However, centuries before, prehistoric peoples lived in the area, obtaining obsidian for arrow and spear points from the Mineral Mountains. Later, the area became home to Paiute Indians. Franciscan Friars Dominguez and Escalante passed through the area in October 1776."
