  • MULE DEER Units 114-115
    Nevada Hunter Information Sheet MULE DEER Units 114-115 LOCATION: Eastern White Pine County – Snake Range. Please see unit descriptions in the Nevada Hunt Book. ELEVATION: From 5,100' in Snake Valley to 12,050' on Mount Moriah. TERRAIN: Gentle to extremely difficult. VEGETATION: Ranges from salt-desert shrub on some valley floors through sage and mixed brush, pinyon/juniper, mountain mahogany and aspen types at mid elevations to aspen/fir/spruce/limber pine/bristlecone pine at higher elevations. Mountainous areas support forest types more than brush, with pinyon and juniper dominating many areas between 6,500’ and 8,000’. Aspen is a minor component in both units. LAND STATUS: The majority of deer habitat is public land administered by either the BLM Ely Field Office or the Ely Ranger District of the Humboldt-Toiyabe National Forest (USFS). Hunting is not permitted on National Park Service lands (Great Basin National Park) located in Unit 115. Note: In 2006, Congress added 11,000 acres to the Mt. Moriah Wilderness in Unit 114 and created a new wilderness area (69,000 acres) on the south end of Unit 115. Vehicles and mechanized equipment, including wheeled game carriers are prohibited in wilderness areas. Contact the Federal Land Management Agency responsible for the area you intend to hunt for more information. Most private land is located on valley bottoms and benches. Private lands do not restrict access to public land. HUNTER ACCESS: Good to fair, based on weather and ground conditions. Access to Unit 114 can be impacted by winter storms. Motorized access is limited by existing roads, terrain and wilderness designations.

  • A History of Juab County, Utah Centennial County History Series
    A HISTORY OF fjuab County Pearl D. Wilson with June McNulty and David Hampshire UTAH CENTENNIAL COUNTY HISTORY SERIES A HISTORY OF JuaB County Pearl D. Wilson with June McNulty and David Hampshire luab County, one of Utah's earliest created counties, sits along the strategic north-south corridor of the state. Prehistoric and Native American Indian cultures roamed there, as did early Spanish priests and explorers, who left an important record of the area. Trappers and traders wandered the mountains and deserts that create stark contrasts in this geo­ graphically diverse county. Mark Twain, an early traveler through parts of luab, penned interesting insights of the county, which contained portions of the Pony Express and Overland Stage routes. Mormon pioneers arrived to establish farms and ranches. This was followed by the build­ ing of railroads and mineral exploration. Rail traffic for a vast region centered in Nephi, labeled "Little Chicago." To the west, the Tintic Mining District rose as one of Utah's richest gold and silver mining areas, attract­ ing a more ethnically diverse population. From majestic Mount Nebo to streams and lakes and the vast sand dunes of west Juab, the county contains many recreational possibili­ ties. Juab County is rich in history, geogra­ phy, and tradition; this book tells its story. ISBN: 0-913738-20-4 A HISTORY OF Juab County A HISTORY OF ffuaB County Pearl D.

  • Petrogenesis of the Oligocene East Tintic
    PETROGENESIS OF THE OLIGOCENE EAST TINTIC VOLCbyANIC FIELD, UTAH Daniel K. Moore1, Jeffrey D. Keith2, Eric H. Christiansen2, Choon-Sik Kim3, David G. Tingey2, Stephen T. Nelson2, and Douglas S. Flamm2 ABSTRACT The early Oligocene East Tintic volcanic field of central Utah, located near the eastern margin of the Basin and Range Province, consists of mafic to silicic volcanic (mostly intermediate-composition lava flows) and shallow intrusive rocks associated with the formation of small, nested calderas. Radiometric ages establish a minimum age for initiation (34.94 ± 0.10 Ma) and cessation (32.70 ± 0.28 Ma) of East Tintic magmatism. The igneous rocks of the field are calc-alkalic, potassic, silica-oversaturated, and met- aluminous, and can be categorized into the following three compositional groups: the shoshonite-trachyte series, the trachyandesite series, and the rhyolite series. Based on composition and phenocryst assemblage, the shoshonite-trachyte series is divided into two groups: a clinopyroxene group and a two-pyroxene group. The rhyolite series consists of three field units: the Packard Quartz Latite, the Fernow Quartz Latite, and the rhyolite of Keystone Springs. The trachyandesite series is by far the most voluminous. This series is also subdivided into a clinopyroxene group and a two-pyroxene group. Temperature and oxygen fugacity estimates indicate that shoshonite-trachyte series magmas were the hottest and least oxidizing and that two-pyroxene trachyandesite series magmas were the coolest and most oxidizing. Clinopyroxene shoshonite-trachyte series magma evolved mainly by fractional crystallization. The high K2O, Rb, and Al2O3/CaO ratios and modest SiO2 enrichment of these rocks appear to result from extensive, high-pressure fractional crystallization of clinopyroxene (without plagioclase).
