  • A History of Beaver County, Utah Centennial County History Series
    A HISTORY OF 'Beaver County Martha Sonntag Bradley UTAH CENTENNIAL COUNTY HISTORY SERIES A HISTORY OF 'Beaver County Martha Sonntag Bradley 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. The Mormon settlement of Beaver devel­ oped at the foot of the Tushar Mountains. In 1859 the community of Minersville was es­ tablished, and residents farmed, raised live­ stock, and mined the lead deposits there. In the last quarter of the nineteenth century the Mineral Mountains and other locations in the county saw extensive mining develop­ ment, particularly in the towns of Frisco and Newhouse. Mining activities were given a boost with the completion of the Utah South­ ern Railroad to Milford in 1880. The birth­ place of both famous western outlaw Butch Cassidy and inventor of television Philo T. Farnsworth, Beaver County is rich in history, historic buildings, and mineral treasures.

Joint patterns in the Mineral Mountains intrusive complex and their roles in subsequent deformation and magmatism C1 JOINT PATTERNS IN THE MINERAL MOUNTAINS INTRUSIVE COMPLEX AND THEIR ROLES IN SUBSEQUENT DEFORMATION AND MAGMATISM by John M. Bartley ABSTRACT Granitic rocks intersected by drill holes in the Utah FORGE site in Milford Valley strongly resemble the Oligocene-Miocene Mineral Mountains batholith and belong to the same structural block as the Mineral Mountains. Thus, the Mineral Mountains batholith and the FORGE reservoir may share the same joint pattern. Fractures in the Mineral Mountains plutonic complex were mapped in seven 0.03–0.08 km2 areas in the northern half of the range to document orientations, spacing, continuity, intersection relationships, and orientations of slickenlines where present.
