Exploring Questions Of Tectonic Geomorphology In The Bear River Range, Utah Using Terrain Analysis And Reconstruction, Edward M. Grasinger
Exploring Questions Of Tectonic Geomorphology In The Bear River Range, Utah Using Terrain Analysis And Reconstruction, Edward M. Grasinger
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Despite a long tradition of geologic studies in the region surrounding Utah State University, there remain unexplored questions and unutilized approaches for understanding the landscape evolution of the Bear River Range. A large-scale reconstruction of the East Cache fault system can be useful in estimating the total displacement of the fault, its geologic longevity, and total energy involved. Likewise, an analysis of reach-scale features of the Logan River can explore how tectonics and bedrock type affect the patterns and history of the river. Geographic Information Systems (GIS) software is useful in reconstructing, visualizing, and measuring such geomorphological features and changes …
Taphonomy Of Late Jurassic (Tithonian) Morrison Formation Apatosaurus Sp. Vertebrae Found Associated With Teeth From Allosaurus Sp. And Ceratosaurus Sp., And Body Size Extrapolation From The Associated Theropod Teeth., Greg C. Agyan
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
An Apatosaurus sp. locality from Dinosaur National Monument designated DNM-15 was excavated in 1985, and associated with two Allosaurus teeth and one Ceratosaurus tooth that were near one of the caudal vertebrae. The Ceratosaurus tooth was buried between an overlying rib and that same caudal vertebra. The caudal vertebrae of the DNM-15 Apatosaurus were intact and articulated, but the anterior skeleton was mostly absent, with a row of articulated sacral vertebrae in close association with a femur. Two other Allosaurus teeth were reported near the preserved ilium of the Apatosaurus, but they could not be located in the collections. …
Hazard Analysis Of A Segment Of Highway Sr-12 Through Bryce Canyon National Park, Southern Utah, Tomsen Reed
Hazard Analysis Of A Segment Of Highway Sr-12 Through Bryce Canyon National Park, Southern Utah, Tomsen Reed
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Over 2.6 million people travel along highway SR-12, a National Scenic Byway, through Bryce Canyon in southern Utah each year. This highway is a major thoroughfare for tourists traveling to Bryce Canyon National Park, Grand Staircase-Escalante National Monument, and other scenic attractions. SR-12 is susceptible to rockfall and landslide hazards where it descends from the Paunsaugunt Plateau into Tropic Canyon, and these hazards have potential consequences of economic loss due to travel delays for tourists and commodities, and possible loss of life. Rockfall could have devastating effects at this location because of the traffic volume, sharp turns, low visibility, and …
Analysis Of The Parkway Drive Landslide, North Salt Lake, Ut, Brianna V. Hill
Analysis Of The Parkway Drive Landslide, North Salt Lake, Ut, Brianna V. Hill
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
On August 5th, 2014, a hillside failed behind a North Salt Lake City, UT neighborhood threatening several homes. Aerial Photography, Digital Elevation Models (DEM), geochemistry, rain gage and seismic data were used to test the influence of contributing factors in this landslide failure. Aerial photographs available from 1993 to present were examined for signs of tension cracks suggesting impending ground motion, as well as documentation of human modification along the hillslope. Repeat DEM analysis of elevation and slope of the hillside before and after the slide were examined to characterize the pre-failure hillslope and subsequent landslide. Geochemical analyses …
The Dynamic Relationship Between The Bear River, Quaternary Basaltic Center, Normal Faults, And The Resulting Rearrangement Of Rivers In The Northeast Edge Of The Great Basin, Southeast Idaho, Brady Utley
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The objective of this research project in Gem Valley graben, southeast Idaho is to identify the location, age and history of the Quaternary diversion of the Bear River into paleo-Lake Thatcher, and then into the Lake Bonneville basin from the Columbia River basin. Mapping, geochemical analysis, cross-cutting relationships, and five new age determinations, together with prior published research, shed new light on the complex history of interaction between the volcanic rocks, rivers, lakes, and faults in Gem Valley. Research goals were to test the hypothesis that local faulting and volcanism drove the diversion of the Bear River and controlled the …
Stratigraphy, Petrology, And Paleontology Of The Late Cretaceous Campanian Mesaverde Group In Northeastern Utah, Christopher Ward
Stratigraphy, Petrology, And Paleontology Of The Late Cretaceous Campanian Mesaverde Group In Northeastern Utah, Christopher Ward
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
This project examines a poorly studied sandstone ridge called Snake John Reef located 22 miles southeast of Vernal, in northeastern Utah. Previously this ridge was mapped as exposures of late Cretaceous, undifferentiated Mesaverde Group, and recently unidentified dinosaur fossils have been found along the ridge by the Utah Field House of Natural History State Park Museum. Stratigraphic sections, petrographic thin sections, and collection and study of fossils from Snake John Reef were undertaken to understand the stratigraphic relationship as well as to reconstruct the depositional environment of the dinosaur bearing units. Snake John Reef represents exposures of three late Cretaceous …
Stratigraphy Of The Middle Cambrian Lincoln Peak Formation And Evolution Of The House Range Embayment, Eastern Nevada, Ibrahim Zallum
Stratigraphy Of The Middle Cambrian Lincoln Peak Formation And Evolution Of The House Range Embayment, Eastern Nevada, Ibrahim Zallum
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
This study examined the Middle Cambrian (c. 500 MA) Lincoln Peak Formation and Patterson Pass Shale. The initial goal was to create a stratigraphic model for these units. This model was then compared to those from already studied units in western Utah, which combined with the Nevada units form the rock record of an ancient feature known as the House Range Embayment, which was an area of greater water depth superimposed on the continental shelf. This study found that the Nevada units exhibit a series of depositional sequences similar to those in western Utah, but at a lower resolution. This …
A Petrographic Analysis Of The Relationship Between Porosity And Organic Matter In The Permian Phosphoria Formation Of Northeastern Utah, Larry Tackett
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The Permian Phosphoria Formation is a reservoir for oil and gas in the western United States, as well as a major source of phosphate. This study examined the relationship between phosphate richness and porosity exhibited in the formation. Petrographic analysis was carried out on rock samples collected from the Phosphoria (Park City) Formation located north of Vernal, Utah, on the southern flank of the Uinta Mountains.
The analysis demonstrated an inverse relationship between organic richness and porosity in the Phosphoria Formation. Porosity is controlled by lithology, amount of cementation, weathering, and amount of fecal pellets, which are the source of …
A Study Of The Bioherms Of The Early Ordovician Garden City Formation And A Literature Review Of Early Ordovician Organic Buildups, Heidi Pearce
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
During the Early Ordovician organic buildups formed in shallow seas across the world. This project contains a literature review on these organic buildups with a focus on those occurring in the warm, shallow seas of North America, but also includes a study on organic buildups formed in the cold water region of Russia. The goal of the study was to characterize these Early Ordovician organic buildups in order to identify similarities and differences in their occurrence. The second part of this project is a preliminary study on organic buildups occurring in the Early Ordovician Garden City Formation in Boss Canyon, …
Using Real-World Data As A Basis For Problem-Based Learning: Investigating Preservation Biases Of Fish In Fossil Butte National Monument, Blair Larsen
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
This project examined the design and development of an online problem-based learning module to teach earth-system science to K-12 educators. The module revolved around identifying earth sphere (lithosphere, hydrosphere, biosphere and atmosphere) interactions needed to produce mass fish mortality layers found in the Green River Formation at Fossil Butte National Monument. Students investigated the unique earth sphere combinations needed to produce mass fish mortality layers, reflected on the formation of such deposits, and examined the impact of these earth spheres on the earth system. As a supplement to the course, the students also analyzed data on fossils collected from a …
Investigations Into Mapping Lava Flows In The Snake River Plain, Idaho, Vinita Ruth Hobson-Broko
Investigations Into Mapping Lava Flows In The Snake River Plain, Idaho, Vinita Ruth Hobson-Broko
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The origin of the Snake River plain continues to be debated, but the plume model is most popular at the current time. Some theories, such as meteorite impact, have been excluded, but the remaining theories require more scrutiny.
Various methods of examining phenomena in the Snake River Plain were employed. Unsupervised classification of Landsat ETM data indicates that spectra can be used to differentiate between flows. However, photographs of flows at Craters of the Moon National Monument show wide variations in texture and color within a single flow. Vegetation grows preferentially on the smoother pahoehoe slabs and significantly impacting the …
