All U.S. Government Documents (Utah Regional Depository)
The Utah/western Colorado area of the Rocky Mountain Region has adequate coal and water resources to support additional thermal generation plants beyond those already in service. Also within the region are several sites suitable for large-sized hydroelectric pumped-storage projects for purposes of supplying peaking power. The close proximity of these types of electric generating facilities is desirable in providing offpeak energy during the pumping cycle for the pumped-storage units. Considering that the potential capacity of each type of generation is in the 500 to 1,000 (two units) MW range per site and would require major extra-high-voltage (EHV) transmission developments, it …

Application Of Mineral-Solution Equilibria To The Search For Sanstone-Type Uranium Deposits In The Beaver Basin, Utah, W. R. Miller, J. B. Mchugh, U.S. Geological Survey
All U.S. Government Documents (Utah Regional Depository)
An improved computer modeling program was used to calculate the saturation indexes of 50 waters from the Beaver basin in west-central Utah with respect to uraninite and coffinite. The mineral-solution study showed that the chemical environment of parts of the Beaver basin is favorable for the occurrence of sandstone-type uranium deposits. The ground waters from several areas are supersaturated with respect to uraninite and coffinite. Two areas, in particular, an area west of the town of Beaver and an area near the settlement of Manderfield, have been identified as most favorable for exploration. The methods described in this study can …

Shallow Electromagnetic Data From Three Known Fault Zones In The Paradox Basin, Utah, Raymond D. Watts, U.S. Geological Survey
All U.S. Government Documents (Utah Regional Depository)
This report describes a preliminary investigation of the effectiveness of two electromagnetic exploration methods as means of finding unmapped faults in the Paradox Basin environment. Results indicate that the Very Low Frequency (VLF method is useful. VLF profiles were measured across three known fault traces near Gibson Dome, San Juan County, Utah. Each fault or set of faults generated a significant anomaly. In some cases, the anomaly due to the fault was superimposed on a larger scale anomaly caused by the transition from unaltered rocks away from the fault to altered rocks in or on one side of the fault …

Geochemical Results From A Rock Geochemical Survey In The Mount Belknap Caldera Vicinity, Utah, Robert E. Tucker, William R. Miller, J. N. Motooka, U.S. Geological Survey
All U.S. Government Documents (Utah Regional Depository)
Rock, stream-sediment, and hydrogeochemical surveys were conducted in the Mount Belknap caldera area, south-central Utah, during the summer of 1979. The presence of leucocratic rocks and relatively high concentrations of the elements Nb, Be, Ga, Y, Pb, Sn, Mo, and F with corresponding low concentrations of the elements Ba, Mg, Ca, Fe, Sr, and Cu suggests that late phase highly differentiated felsic magmas were intruded and (or) erupted in the caldera vicinity. The presence of Mo and Sn in the rocks and F in the water samples suggest that the ore elements were concentrated, first in residual fluids in the …

Visual Impacts Of Forest Management Activities: Findings On Public Preferences, United States Department Of Agriculture, Forest Service
Forestry
A major concern of forest land managers is the visual impact that activities such as timber harvest, road building, and mining have on the forest landscape. Management of the visual resource is a regular part of planning on National Forests, and many other public and private forest land managers are increasing their efforts to protect and enhance this resource. The Forest Residue and Harvesting Research Program at the Intermountain Station includes studies of the impact of harvest and roading activities on visual quality. Preliminary results were reported earlier (Schweitzer, Ullrich, and Benson 1976). This report updates earlier findings and presents …

The Chatanika radar has been used to measure the ratio of atomic (O+) ions to molecular (O2 +, NO+) ions in the high-latitude ionosphere. The radar results agreed well with simultaneous in situ rocket data, giving confidence in the radar method of deducing ion composition. Measurements made over long periods of time show seasonal variations, diurnal variations, and variations due to auroral processes. The transition altitude, where the number densities of atomic and molecular ions are equal, is a convenient parameter for describing the composition variation with altitude or ‘composition altitude profile.’ The transition …

An intense burst of VLF waves, at frequencies just above the local proton gyrofrequency, was observed shortly after each of two intense bursts of field‐aligned suprathermal electrons (E < 250eV) by instruments carried on a sounding rocket flown in diffuse aurora. If the two phenomena are associated with each other, the implication is that the electron acceleration occurred nearby, in a relatively small volume.

In this preliminary report on low-energy (0.3 to 3 eV) secondary electrons in the auroral E layer (90 to 150 km), we compare intensities of plasma lines observed with the Chatanika radar to theoretical predictions obtained from a detailed numerical model. The model calculations are initiated with a flux of energetic auroral primary electrons which enter the atmosphere and lose energy to electrons, ions, and neutrals through a combination of elastic and inelastic collisions. This flux is chosen in order that the total calculated ionization rate matches one that is deduced from the radar measurements. From these same calculations the …
