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 …

Managing Lodgepole Pine To Yield Merchantable Thinning Products And Attain Sawtimber Rotations, United States Department Of Agriculture, Forest Service

Forestry

This paper suggests solutions for a longstanding problem in managing lodgepole pine forests -- that of managing individual stands to reach their planned rotation age, despite serious hazard from bark beetles and wildfire. The management regimes presented yield merchantable thinning products. The 80-year sawtimber rotation can be achieved using these management recommendations. Thinning at 30 years of age is central to achieving the recommended alternative management regimes. The authors suggest that agencies give roundwood operators a portion of the thinning stemwood as payment. Management regimes that provide attainable rotations are presented in summary tables, by three site index classes and …

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 …

Discussion And Measurement Of Soil Erosion In Iceland, Kimberly Jane Richardson

Undergraduate Honors Capstone Projects

Soil erosion has occurred since the beginning of time. It is a natural process, but one that has been increasing at an alarming rate. Once soil is eroded--whether it is blown out to sea or washed down a river to sedimentize a lake--it is lost. It is almost impossible to reestablish similar soil components and characteristics in a given system. Since soil and vegetation reestablishment is expensive, the prevention of soil erosion by controlling its causes has become the most cost-effective reclamation effort.

After spending six months in Iceland, I wrote this paper on the unique erosion problems facing that …

In Utah, these areas are called drinking water source protection (DWSP) zones. Zones Two and Three are delineated according to analytical or numerical techniques, which are based on hydrogeological and time-of-travel data, as well as recharge information, accumulated through the use of hydrogeologic and hydrochemical techniques. The primary conclusions of this research are:

1. A fence diagram and site hydrostratigraphic diagram show that the hydrogeology is more complex than previously has been thought. The principal aquifer at the target well site comprises a sequence …

Magnitude Of Displacement And Styles Of Deformation On The Paris And Laketown Thrust Faults, Northern Utah, Richard D. Kendrick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Surface geology is combined with abundant industry seismic-reflection and drill­-hole data in the central Bear River Range and Bear Lake Plateau to depict the forms and interactions of the Paris-Woodruff-Willard, Laketown-Meade-Home Canyon, and Crawford thrust faults. Displacement on the Paris thrust diminished to the south, and died out in splays where displacement was transferred to the Willard thrust. West of Woodruff, Utah, splays of the Laketown thrust deformed a complex footwall imbricate of the Willard thrust. To the east, a major northeast-striking Crawford thrust splay exhibits a change in slip vectors from east to southeast. Reorientation of these slip vectors …

The Tectonic Evolution Of The Panther Creek Half-Graben In East-Central Idaho, Brian F. Hammond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An integrated field, petrographic, structural, and geophysical analysis of the Panther Creek half-graben (PCHG), in east-central Idaho, was undertaken to determine its tectonic origin. Two competing theories as to the origin of the PCHG exist. One suggests that it formed as part of the TransChallis fault system (TCFS), a system of northeast-trending normal faults, eruptive centers, and graben that formed in Middle Eocene time. The graben of this system are bounded by northeast-striking normal faults, and show evidence of syn-tectonic deposition of basin-filling volcanic strata. The other theory suggests that the PCHG may have evolved as a result of a …

Sedimentology And Foraminiferal Taphonomy In Siliciclastic Environments: The Northern Gulf Of California, Mexico, Liping Zhang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Holocene sediments from intertidal and shallow subtidal zones in Bahia la Choya, Mexico exhibit significant differences based on their mineralogical content, constituent composition, textural parameters, and foraminiferal assemblages. The intertidal sediments are characterized by low calcium carbonate content, being dominated by quartz, and are moderately well sorted and coarse skewed with a fine mean grain size {M_z = 2.73 phi}. Total numbers {living and dead} of benthonic Foraminifera per ml of sediment are relatively low (12/ml) in the intertidal zones. In contrast, the subtidal sediments are characterized by high calcium carbonate content, being dominated by molluscan shell fragments, and …

The primary conclusions of this research are: 1) Fault zones can be separated into subzones of protolith, damaged zone , and gouge /cataclasite, based on physical morphology and permeability structure. At deep structural levels, gouge/cataclasite zones are more evolved (thicker with increased grain size reduction) due to strain localization, higher pressure and …

Predicting Regeneration Establishment With The Prognosis Model, United States Department Of Agriculture, Forest Service

Forestry

Conifer establishment following regeneration timber harvests is predicted by version 2 of the Regeneration Establishment Model, a submodel of the Prognosis Model. The regeneration model covers 10 species for forests in Montana, central Idaho, and northern Idaho. Most harvest and site preparation methods can be simulated so that alternative treatments can be evaluated. Also included in the model is the influence of western spruce budworm (Choristoneura accidentalis) on regeneration success. The model predicts the probability of stocking, seedling density, species composition, and seedling heights 2 to 20 years after harvest. This paper describes the study design, equation development, model formulation, …

Evaluation Of Roadside Stabilization And Beautification Plantings In South-Central Utah, United States Department Of Agriculture, Forest Service

Conceptual Evaluation Of Regional Ground-Water Flow In The Carbonate-Rock Province Of The Great Basin, Nevada, Utah, And Adjacent States, United States Geological Survey

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

The carbonate-rock province of the Great Basin, mainly in eastern Nevada and western Utah, is characterized by thick sequences of carbonate rocks of Paleozoic age. These rocks overlie clastic and crystalline rocks of Cambrian and Precambrian age, respectively. Since the carbonate rocks were deposited, structural compression and extension, intrusive and volcanic episodes, and erosion have greatly modified their distribution and thickness, and a variety of younger rocks and deposits have been emplaced within and above them. The most notable present-day physiographic features in the area are associated with normal faults caused by tensional forces during Tertiary time: The faulting has …
