An Environmental History Of The Bear River Range, 1860-1910, Bradley Paul Hansen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study of environmental history suggests that nature and culture change all the time, but that the rate and scale of such change can vary enormously. During the late 19th and early 20th centuries, Anglo settlement in the American West transformed landscapes and ecologies, creating new and complex environmental problems. This transformation was particularly impressive in Cache Valley, Utah's Bear River Range. From 1860 to 1910, Mormon settlers overused or misused the Bear River Range's lumber, grazing forage, wild game, and water resources and introduced invasive plant and animal species throughout the area.

By the turn of the 20th century, …

Effects Of Cache Valley Particulate Matter On Human Lung Cells, Todd L. Watterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the wintertime, residents of the Cache Valley are very aware of the poor air quality that occurs during cold-air inversion episodes. If one somehow avoids the radio and television announcements as well as the electronic roadside signs indicating poor air quality and encouraging less driving, one need only to look upward toward the mountains that surround the valley and notice the lack of daytime visibility. This lack of visibility and health warnings are due to particulate air pollution or particulate matter (PM). PM is only one of many types of regulated air pollution but is the one that occurs …

The People Of Bear Hunter Speak: Oral Histories Of The Cache Valley Shoshones Regarding The Bear River Massacre, Aaron L. Crawford

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Cache Valley Shoshone are the survivors of the Bear River Massacre, where a battle between a group of US. volunteer troops from California and a Shoshone village degenerated into the worst Indian massacre in US. history, resulting in the deaths of over 200 Shoshones. The massacre occurred due to increasing tensions over land use between the Shoshones and the Mormon settlers. Following the massacre, the Shoshones attempted settling in several different locations in Box Elder County, eventually finding a home in Washakie, Utah. However, the LDS Church sold the land where the city of Washakie sat, forcing the Shoshones …

The Cache Valley Shoshones: Cultural Change, Subsistence, And Resistance, To 1870, John W. Heaton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the eighteenth and nineteenth centuries, the xii Shoshones of Cache Valley evolved from scattered pedestrian hunter-gatherers to large, armed, mounted bands that hunted and gathered from the Great Basin to the Plains. Trade with European Americans helped initiate this evolution. However, Shoshones did not respond passively to the presence of European Americans. Shoshones actively sought change, and incorporated trade goods into their culture within a Shoshone context. They adapted to each wave of European Americans that they encountered. When Mormons dispossessed them of their land, Cache Valley Shoshones resisted by going on the offensive. Finally overwhelmed, the remnants of …

Nature's Second Course: Water Culture In The Mormon Communities Of Cache Valley, Utah, 1860-1916, Kathryn T. Morse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nineteenth-century Mormon settlers in Utah combined a unique set of religious beliefs with a fervent agrarianism and a strong sense of community. They encountered a specific arid environment along the Wasatch Front. A distinctive cultural set of irrigation institutions and practices developed out of the complex interchanges between nature and culture in Cache Valley, Utah, between 1860 and 1916. The structure of water flow, and conflicts over water rights and responsibilities, reflected the fundamental tensions within Mormon communities between individual gain and collective progress; it also reflected the patriarchal essence of Mormon culture.

The season-to-season workings of irrigation institutions that …

Martin Harris In Cache Valley - Events And Influence, Scott R. Shelton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The well-known Mormon historical figure, Martin Harris, spent the last five years of his life in Cache Valley, Utah. Most of the research done to this point on this man, who claimed to have seen angels and heard the voice of God, has been on the early years of LDS Church history during which Harris was intimately involved with the coming forth of The Book of Mormon. Little has been done on his years in Cache Valley, except for collections of affidavits concerning his testimony.

This study gives a brief overview of Harris's first eighty-seven years, his journey to …

Development Of A Liquefaction Opportunity Map For Cache Valley, Utah, Richard J. Greenwood

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A liquefaction opportunity map was developed for Cache Valley, Utah. The study was the initial phase to determine the potential for liquefaction in Cache Valley.

The method used in this study to develop the liquefaction opportunity map was based on a procedure developed by Youd and Perkins (1977).

This opportunity map is proposed to be combined with a map delineating liquefaction susceptible soils to produce a liquefaction potential map. The liquefaction susceptibility map is being developed in a companion study.

The liquefaction potential map will assist in the evaluation of earthquake response in general and microzonation in particular. The liquefaction …

A Mesoscale Radiation Study Of The Cache Valley, Nolasco G. Baldazo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The radiation climate of Cache Valley was established from the continuous recordings of global and diffuse sky radiation at Utah State University campus from June 1968 to July 1969 and August 1968 to July 1969, respectively. The influence of topographic features during summer and winter conditions at seven representative locations running on an east-west direction across the valley were determined by making short term measurements on clear days.

A comparison of the clear day average global radiation on approximate dates of the same solar declination shows higher values during late winter and spring than the values during late summer and …

Overwintering Of Erwinia Amylovora Inside Living Host Tissue In Cache Valley, Utah, G. Doyle Morrill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Experiments were conducted to see if Erwinia amylovora (Burrill) Winslow et al. overwinters inside living host tissue in Utah. Bacteria, collected from apple, pear, mountain ash, chokecherry and Pyracantha, were used in the experiment. Isolates taken from buds and inner bark plated on nutrient yeast dextrose agar, we re tested by serological and bacteriophage techniques. Those showing positive tests were then inoculated into Bartlett pear seedlings to test virulence.

Both virulent and avirulent isolates were isolated from each species of plant in the experiment. Pathogenic bacteria were isolated from diseased tissue near cankers, as well as from apparently healthy inner …

Comparisons Of Phytoseiid Predator Populations In Sprayed And Unsprayed Apple Orchards In Cache Valley, Utah, Yeboa A. Dodoo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A comparative study of phytoseiid populations was made of two well-cultivated and regularly sprayed apple orchards with two unsprayed orchards in Cache Valley, northern Utah.

Two phytoseiid species, Typhlodromus mcgregori Chant and T. occidentalis Nesbitt were observed on the apple leaves, under the bark, and occasionally in the litter and soil. Amblyseius cucumeris (Oudemans) occurred in the soil and litter and occasionally under bark. T. mcgregori was dominant in the unsprayed orchards, and T. occidentalis in the sprayed.

Of the phytophagous mites, which served as food for the phytoseiids, the two-spotted mite, Tetranychus urticae Koch was dominant. Other phytophagous mites …

A Study Of Farm Mechanics On Typical Farms In The North Cache High School District, Clifford G. Hansen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The farmers of today are faced with many more and varied problems than were their grandfathers. This is in part due to the rapid mechanization of farming that has been developing during the past three decades. This movement for increased mechanization in farming presents a new challenge to farmers because of their responsibility in caring for farm machinery and maintaining it in an efficient operating condition. In effect, this means that the efficient farmer must devote an increasing amount of time and attention to the managerial and operative skills connected with mechanized farming. Moreover, he must acquire tools and equipment …
