Mafic Volcanism In The Colorado Plateau: Basin And Range Transition Zone, Hurricane, Utah, Alexander Sanchez

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Hurricane volcanic field (HVF) is a small-volume (0.48 km³) mafic volcanic field in the Colorado Plateau/Basin & Range Transition Zone located in the eastern part of the St. George basin in southwestern Utah. Strombolian-Hawaiian style eruptions produced thin (10 m) a'a lava flows and cinder (scoria) cones composed of vesicular basalt, bombs and agglutinate. Radiometric dating and geologic relationships demonstrate that the HVF formed over a period of at least 100,000 years. In the upper crust, magma probably rose along joints in sedimentary rocks because chains of volcanic vents follow joint orientation maxima in sedimentary rocks.

Conference organizers and/or faculty included University of Colorado School of Law professors David H. Getches, Lawrence J. MacDonnell, Teresa A. Rice, Elizabeth A. Rieke and Charles F. Wilkinson.

Sustainable development is on the policy agenda for the '90s. What does sustainability mean? Is it a realistic concept? Are water rights compatible with sustainable use? The Center's 16th annual summer conference will explore the meaning of sustainability in the context of the West's demands, development, and natural values. Presentations by leading experts will address the broad concept of sustainable development, with a particular look at Arizona's experience. The focus will be …

Wild Ungulate Depredation On Winter Wheat: Effects On Grain Yield, Dennis D. Austin, Philip J. Urness

Great Plains Wildlife Damage Control Workshop Proceedings

The effects of big game grazing of winter wheat on grain yield were studied during 12 trials in northern Utah between 1990-92. Differences in yield were measured for each trial using 20 sets of 1-m² plots protected and variously grazed by mule deer (Odocoileus hemionus), pronghorn (Antilocapra americana) and Rocky Mountain elk (Cervus elaphus) in a randomized block design along the edges of sampled fields. Plots were hand cut at the beginning of commercial harvest. Grazing impacts were indexed by nighttime counts of game animals, pellet-group counts, and ocular estimates of percent track …

Flood Insurance Study, Town Of Joseph, Utah, Sevier County, Federal Emergency Management Agency

All U.S. Government Documents (Utah Regional Depository)

This Flood Insurance Study revises and updates a previous flood Insurance Rate Map for the Town of Joseph, Utah. This information will be used by the Town to update existing floodplain regulations as part of the Regular Phase of the National Flood Insurance Program (NFIP). The information will also be used by local and regional planners to further promote sound land use and floodplain development.

Hydrocarbons And Mineral Resources Of The Uinta Basin, Utah And Colorado, United States Department Of The Interior, Indian Affairs Bureau

Mines and Mineral Resources

The Uinta Basin holds special fascination for economic geologists because of its rich and diverse assemblage of mineral and hydrocarbon resources. Due to their presence in rocks of the basin, much effort has been put into assessing and exploiting uranium, phosphate, gold, copper, coal, and evaporite minerals. However, the basin is probably best noted for its extensive and very rich accumulations of hydrocarbons such as, oil, gas, bituminous sandstones, oil shale (shale oil), and gilsonite and other solid and semi-solid hydrocarbon species. More importantly, several of these commodities have proven to be a major source of wealth and resources for …

Holocene Archeology Near Squaw Butte, Canyonlands National Park, Utah

All U.S. Government Documents (Utah Regional Depository)

This document is the final technical report of cultural resources investigations in the Needles District of Canyonlands National Park, southeastern Utah. These investigations were part of the multiyear Canyonlands Archeological Project. Inventory of 878 acres in the Squaw Butte Area revealed 80 sites which were occupied by Archaic people during all phases of the Archaic period, aborigines of unknown cultural affiliation during the Early Formative period, Mesa Verde Anasazi during Pueblo III or late Pueblo II-III, and the Navajo during historic or modern times. Paleoindians may have also been in the general area, if not the actual project area. Limited …
