The Mt. Bellview prospect is located in the Elk Mountains of Gunnison County, approximately 12 miles north of Crested Butte, Colorado (Figure 1). Geologic mapping by Mutschler (1970) revealed that an igneous complex had intruded and hornfelsed the Mancos Shale in the Mt. Belleview area. The complex

As human population and concomitant development increase, human-caused disturbances play an ever larger role in the fitness of wildlife. An increasing number of studies have implicated anthropogenic disturbance in having harmful effects on birds and other wildlife. Most studies, however, concentrate

This thesis explores two institutional frameworks utilized in the governance of water in the Southwest of the United States through how they deliver, or fail to deliver, complex equity. These are (1) the legal framework and (2) cooperative agreements. This is done through a case study in the Roaring

For generations, Latinx women have often been expected to uphold the expectations of

The story of the advancing American frontier has unending interest. Perhaps one of the most colorful and unusual frontier developments was that of the mining frontier in the Rocky Mountains of Colorado. During the years following the discovery of gold in 1858 and the early 1880's occurred an almost

This thesis explores preservation issues regarding modernist architecture in Chicago. As urban and public history research, the project examines the new questions brought to the forefront by recent controversies over the preservation of modernist architecture. Modernism, and an "all concrete" varian

This thesis studies the world-building elements of Urban Fantasy, a genre of popular fiction that emerged in the early 1980’s. I examine the genre as a model-variant of the fantastic that uses elements of traditional Fantasy, Science-Fiction, and the Gothic to construct a believable storyworld inhab

Climate models forecast that headwater catchments in the western U.S. will undergo a reduction in snowpack, early season snowmelt, and increases in evapotranspiration. The resulting extended dry season will stress vegetation in mountainous watersheds throughout the Upper Colorado River Basin. We inv

The goal of irrigation scheduling is efficient use of water such that water is applied to the field for optimal crop production. Previous studies have optimized irrigation scheduling using different models to manage sprinkler irrigation. This research evaluated approaches for obtaining alfalfa refer

Dryland winter wheat (Triticum aestivum) cropping systems dominate most of the agricultural landscape in Colorado’s semi-arid eastern plains. Since this area’s climate is characterized by frequent heat and drought, it is important to maximize water use efficiency to make agricultural lands as produc

I examined the utility of the strontium isotope (87Sr/86Sr) ratio in fish otoliths to determine the origins and movements of invasive piscivores in the Upper Colorado River Basin (UCRB). My goal was to determine if invasive piscivores entered riverine habitat of endangered fishes in the UCRB by esca

The lure of gold in the great reefs of Johannesburg near the end of the 19th century not only attracted the famous mining barons such as Cecil John Rhodes, Alfred Beit and Barney Barnato: working men also came from far and wide to feed their families with their labour.Among them was my great-grandfa

Siliciclastic sediments of the Proterozoic Uncompahgre Group can be subdivided into stratigraphic units of quartzite (Q) and pelite (P); these units include a basal, fining- and thinning-upward retrogradational sequence (Q1-P1) that records the transition from an alluvial to a shallow-marine setting

The Central Colorado Trough formed as a result of the uplift of the Ancestral Rocky Mountains. With uplift, sediments were eroded from the adjacent highlands and deposited in the trough. The Lower Pennsylvanian stratigraphy of the Central Colorado Trough was determined based on outcrops in the south

The late Paleozoic Cutler Formation, where exposed near the modern-day town of Gateway, Colorado, has traditionally been interpreted as the product of alluvial fan deposition within the easternmost portion of the Paradox Basin. The Paradox Basin formed between the western margin of the Uncompahgre U

Over thirty-five minerals have been identified in the Green River formation of the Piceance Creek Basin, using quantitative X-Ray Diffraction (XRD) bulk analysis.Fifteen major phases occur at over 5 wt% average in 117 samples spanning the thickness of the formation.Integrated data from cores, outcro
