The purpose of this thesis is to describe the early exploration and settlement of the Tooele area, from the time it was first entered by the adventurous fur trappers through the first years of Mormon colonization.

The original purpose of this study was to examine the influences of ecological site, seeding method and planting season on rangeland seeding success within the Tooele Fire Rehabilitation Project (TFRP) in northwestern Utah. The major objective of the TFRP, designed by the USDI Bureau of Land Management, was to establish a permanent cover of 'Nordan' crested wheatgrass (Aqropyron desertorum (Fischer ex Link) Schultes), 'Luna' pubescent wheat grass (Thinopyrum intermedium ssp. barbulatum (Schur) Barkw. and D. R. Dewey) and 'Al kar' tall wheatqrass (Thinopyrum ponticum (Podp.) Barkw. and D. R. Dewey) on approximately 20,000 ha of rangeland burned by a wildfire in July 1983. Thirteen combinations of site, method and planting season were identified within the study area; each was treated as an experimental unit. There were no significant differences (Pi0.05) in seedling densities between these treatment combinations. Means ranged from O to 1.9 seedlings/m2. There was significant variation (Pi0.05) among seedling densities within each treatment combination. Because of low seedling densities and non-uniform seedling establishment patterns, seedings within the study area were failures. Study effort was redirected to identify the causes of seeding failure. viii Among planting seasons and seeding methods, spring plantings and broadcast seeding contributed to failure. Most sites within the study area were suitable for seeding, with the exception of desert shallow loam. This site should not have been seeded because of steep topography and shallow soil. Planting during spring, broadcast seeding and the seeding of low potential sites explained only localized failure, however. The absence of crested wheatgrass seedlings within the study area was a major factor contributing to failure. Only two crested wheatgrass plants were found on a total of 195 permanently established transects. Of the three species seeded, crested wheatgrass was the best adapted to site conditions. Seeding technique was considered the most important factor causing failure. Contract workers on the project had no rangeland seeding experience. Drills were not properly equipped to control seed placement at the proper soil depth. Seeding was done during periods when site conditions were unfavorable. There was no evidence suggesting weather, grasshopper damage or cheatgrass competition caused failure.

The purpose of the study was to determine the incidence of drug abuse among seniors of Tooele High School, Tooele, Utah, and Logan High School, Logan, Utah. The following sub-problems were investigated as a part of this study. 1. The relationship of the incidence of abuse between males and females. 2. The possible influence a university may have upon a neighboring high school , in reference to drug abuse. The data for the purpose of analysis was obtained from answers to the questions used in the questionnaire. The questionnaire consisted of 47 questions. The number of participants included 201 high school seniors at Logan High and 219 from Tooele. The Logan group registered 102 males and 107 females, while the Tooele group accounted for 112 males and 107 females. Those students that were absent on the day the questionnaire was administered were eliminated from the study. DD-5081 punch cards were obtained and used as a means of collecting descriptive analytical data for this study. The results of the questionnaires were recorded upon ffiM answer sheets and were statistically analyzed by the use of computers. Based on analysis of 420 responses the computer provided specific correlation coefficients by use of the Two Way Independent Chi-Square.

The Simpson Mountains have long been of economic interest and have renewed interest in their potential value. Field mapping of the project area redefined structural relationships between stratigraphic units. Geometric and kinematic analysis of structures in the Simpson Mountains show the range is deformed by the three most recent tectonic events: the Sevier Orogeny, the Laramide Orogeny, and Basin and Range Extension. Laramide structures define the range with a significant E-W normal fault and an E-W thrust fault, which are both likely related to Eocene-age igneous intrusions. Principal component analysis (PCA) of regional quartzite X-ray Fluorescence (XRF) data resulted in distinctive populations between the Eureka Quartzite and the Mutual and Prospect Mountain Quartzites. The PCA was paired with petrographic analysis of regional quartzites where samples were diagnostically classified to help validate the PCA results. XRF analysis of volcanic rocks show volcanic arc origin. 40Ar/39Ar dating of the volcanic rocks associated with the intrusions yield new ages of 34.09±0.10 to 37.05±0.06 Ma and 19.11±0.02 to 19.18±0.03. Lithostratigraphy of the map area was validated by identification of fossil samples. The Eocene intrusions are likely sources of mineralization in the range along older Sevier structures.
