Progress On Rock Glacier Research, John F. Shroder Jr., John R. Giardino

Geography and Geology Faculty Publications

This report is an account of research progress on rock glaciers of Afghanistan, Colorado, and Utah. Because of the preliminary nature of this work, some speculation is present; nevertheless, we think there is evidence for each major, new point expressed. The main thesis of our work is that rock glaciers are polygenetic and appear to be part of a continuum of similar landforms grading morphologically and, presumably, mechanically from one type to another type.

Quaternary Rhyolite From The Mineral Mountains, Utah, U.S.A., S. H. Evans, Jr., W. P. Nash, University Of Utah, Department Of Geology And Geophysics

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

A suite of silicic volcanic rocks is associated with the Roosevelt Hot Springs geothermal area in southwestern Utah. The volcanic sequence includes Tertiary rhyolite 8 m.y. old and obsidian, ash and rhyolite of Quaternary age. The Quaternary lavas are characterized by high silica content (76.5% SiO2) and total alkalies in excess of 9 percent. Obsidians commonly contain greater amounts of flourine than water. Two older flows (0.8 m.y.) can be distinguished from younger dome and pyroclastic material (approximately 0.5 m.y.) by subtle differences in their chemistry. The mineralogy of the rhyolites consists of alkali feldspar, plagioclase, and small amounts of …

Some Aspects Of Geochemistry Of The Water And Sediment Of Bear Lake, Idaho-Utah, Richard H. Fuller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Development by man through the last half century has caused a number of changes in Bear Lake. These changes include the diversion of Bear River water into Bear Lake, the pumping of lake water back into the river, and the building of breakwaters and other obstructions along the shore of Bear Lake.

The diversion of Bear River water into the lake has resulted in a yearly addition of an estimated 36,000 metric tons of calcium into the lake, which has caused the precipitation of an estimated minimum 90,000 metric tons of aragonite. The pumping of Bear Lake water back into …

Use Of Selected Macroinvertebrates As Indicators Of Sedimentation Effects On Huntington River, Utah, Michael Kenneth Reichert

Theses and Dissertations

Benthic macroinvertebrate communities of Huntington River, Emery County, Utah were studied to determine effects of sedimentation from construction of Electric Lake Dam, a state highway, and two bridges. Approximately 900 benthic samples were collected from riffle areas above, in, and below the construction zone from January, 1971 to December, 1973. Two settling basins below construction sites were effective in limiting scouring of downstream communities. Heavy silt deposition was limited to a 1-km stream reach. Number of indicators, density, and biomass were reduced in the construction zone during periods of sediment input. During periods of scouring, density and biomass were reduced; …

Conifer Wood From The Upper Jurassic Of Utah; I, Xenoxylon Morrisonense Sp. Nov., William D. Tidwell, David A. Medlyn

Faculty Publications

A new species of conifer wood, Xenoxylon morrisonense, is described from the Morrison Formation on the Colorado Plateau. It is compared with other species of Xenoxylon, with X. latiporosum being the closest. Xenoxylon morrisonense differs from X. latiporosum in its marked indentations, simple pits on the horizontal and tangential walls of ray cells, absence of crassulae, presence of wood parenchyma, and thin borders on podocarpoid type crossfield pits. The origin of the septa in the tracheids is summarized, and the possible affinity of Xenoxylon with the Podocarpaceae is considered.

The Salt Lake Group In Cache Valley, Utah And Idaho, Robert D. Adamson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fluvial and lacustrine sediments of great thickness accumulated in the intermountain basins of the western United States during Tertiary time. The Salt Lake group in northern Utah and parts of surrounding states is a conspicuous stratigraphic unit of these basins. The "beds of light color" in Morgan Valley in the Wasatch Mountains of northern Utah were named the "Salt Lake group" by Hayden (1869) because of similar occurrences in Salt Lake Valley and because he reasoned that the succession could be divided into formations. Similar rocks crop out in Ogden Valley, north of Morgan Valley, and in Cache Valley, Utah …

Laboratory Tests On Gravelly Material For Use In The Pervious Zones Of Newton Dam, Newton Project, Utah, W.G. Holtz

Elusive Documents

A compaction test was performed on the soil (-1/2") material, and mechanical analysis, specific gravity, and percolation-consolidation test was made in a large (19&1/2" diameter) percolator, cylinder and the material was well compacted into the cylinder. A consolidating load equivalent to a 20-foot fill was applied. Because it was believed that some of the fine sand might be transported through the gravel and rock by the percolating water, a 14-mesh screen and a 2-inch later of clear fine gravel (3/16" - 3/8") was placed over the gravelly material being tested. After the percolation-consolidation test was completed, the screen and fine …

The Devonian Of The Bear River Range, Utah, I. Lavell Cooley
