Excerpt: The mountain man of American folklore and history is a man between cultures. Like Janus, the doorkeeper god of the Romans, he is bifrontal, looking back at European, white civilization, and forward toward Indian civilization and culture.

In response to the economic and political upheaval of World War I, Scottish Modernism explored the cultural and linguistic changes of a nation trying to identify itself amidst a world-wide conflict. Scholars and critics have considered Nan Shepherd's fiction in this context—focusing on issues of gender, female identity, language, and land—but have yet to look seriously at her work The Living Mountain and its contributions to the Modernist movement. More recently, critics like Louisa Gairn and Robert MacFarlane have called attention to Shepherd's small but powerful text in an ecocritical and philosophical light, reframing her contribution to issues of Scottish identity from the Modernist era. Ecocriticism is concerned with the importance of place in relation to human conceptions of identity and explores how landscapes, even a mountain, can elucidate understanding of human being. Ontological questions of being have been explored in relation to place and landscape for several centuries and require, or invite, new narratives of the experience of these encounters, which makes present ecocritical studies an ideal place to do so. This thesis examines Nan Shepherd's work in the intersection of ecocriticism and ontology. To understand a mountain as living, a new language and a new ontology of place is required. The work of Gilles Deleuze on immanence becomes crucial to an understanding of why local place and a connection to it creates a deeper understanding of being and of a language that offers a desubjectivized perspective of a shared awareness between matter. In Shepherd's encounters with the organic and the inorganic her language of experience explores an interaction between her own senses and their perception of the mountain's body of elementals, or the means of apprehending the vitality of the mountain as a living thing. An intriguing twenty-first-century conception of place emerges from Shepherd's modernist perspective and reframes how a landscape and inorganic matter can elucidate human being.

The Golden Throne Quadrangle is located within Capitol Reef National Park, south-central Utah. Geologic mapping of this 1:24,000 scale 7.5 minute quadrangle began in 2003 as the National Parks Service desired to have geologic maps at this scale produced within the park. Stratigraphically, ten bedrock formations and ten Quaternary deposits are exposed within the Golden Throne Quadrangle. Geologic formations range in age from Permian to Jurassic. This map contains details not included on previous geologic maps including; the members of the Carmel, Chinle, and Moenkopi Formations. Additionally, the Page Sandstone is herein mapped as an independent unit. Structurally the Golden Throne Quadrangle encompasses most of the southern quarter of the Miners Mountain uplift. The crest of this southwest verging uplift is cut by the left-lateral strike-slip Teasdale Fault zone. Preparation of a cross-section through the axis of the uplift within the quadrangle has not permitted the use of usual faulting and folding mechanisms (i.e. fault-bend folds and fault-propagation folds) for the creation of the uplift. Two structural models can account for the geometries observed in the field. The first model is a high angle reverse basement fault; the second model is a fold over an inverted basin. The Jurassic Page Sandstone, in the Golden Throne Quadrangle, is composed of the Harris Wash and Thousand Pockets Members, which are divided by the Judd Hollow Tongue, a member of the overlying Carmel Formation It represents an erg deposit and is primarily composed of eolian sandstone. Study of the formation within the Golden Throne Quadrangle helped in the understanding of its local characteristics. Previous research has helped to develop a regional stratigraphic framework for the Page Sandstone. This study cannot be easily incorporated into the regional framework of previous studies. In order to fully understand the sedimentology of the Page Sandstone additional research will need to be accomplished.

The Miocene rhyolites of the Spor Mountain Formation hosts the world's largest beryllium deposit which produced 85% of the world's beryllium in 2010. The fresh lava is extremely enriched in Be (up to 75 ppm in matrix glass). We have examined the rhyolite to understand the Be enrichment. The Spor Mountain rhyolite contains ~40% quartz, ~40% sanidine, ~10% biotite, and ~10% plagioclase, along with accessory fluorite, columbite, euxenite, fergusonite, monazite, thorite, and zircon. Two types of rhyolite erupted within the Spor Mountain Formation, a less evolved magma (1150 ppm Rb, 42 ppm Be, 0.68 wt% F in matrix glass) and an evolved magma (1710 ppm Rb, 75 ppm Be, 1.56 wt% F in matrix glass). Eruption temperatures estimated using zircon saturation, feldspar-liquid, two feldspar, and Ti-in-quartz geothermometers converge on 718 °C for the less evolved magma and 682 °C for the evolved magma. Using the Ti-in-Qz equation of Huang and Audetat (2012), the pressure of the Spor Mountain rhyolite system is estimated to be around 2 kbar at 700°C. Water content of the rhyolite melt was less than <5 wt%, based on the presence of all four major mineral phases at 700°C and the magma was water undersaturated (Webster et al., 1987). Viscosity of the rhyolite was about 6.2 log Pa·s for the less evolved rhyolite and 5.8 log Pa·s for the evolved rhyolite. Magma viscosities calculated using the Einstein-Roscoe question suggest the evolved magma has a slightly higher viscosity than the less evolved magma (7.0 log Pa·s in the evolved magma vs 6.7 log Pa·s in the less evolved magma) because of higher phenocryst content. Fluorine lowered the melt viscosity, though not by a significant amount (less than 0.5 log units at 1.7 wt% F). Partition coefficients for 32 elements have been calculated for biotite, for 21 elements for sanidine and plagioclase, and for 6 elements for quartz, using data acquired by laser ablation inductively coupled plasma mass spectrometry. Partition coefficients for feldspars in the Spor Mountain rhyolite are generally higher than other silicic magmas, and lower for biotite. Beryllium is one of the most incompatible trace elements in the Spor Mountain rhyolite, with a bulk partition coefficient <0.1. Volatile content of the melt (specifically F), melt composition, and the low temperature of crystallization act as the major controls of trace element partitioning. Trace element models using these partition coefficients suggests that crystal fractionation is the dominant magmatic enrichment process within the rhyolite, requiring ~45% crystallization (f = 55%) of the observed phenocrysts to get compositions from the less evolved to evolved rhyolite. Accumulation of batches of melt formed by different degrees of partial melting cannot explain the great depletion of compatible elements.

Alpine soils are young, poorly developed soils that occur above treeline. This study investigates soils located in the alpine-subalpine zone of the Wallowa Mountains, northeast Oregon. Parent material, topography, and vegetation are the most influential pedogenic factors in the high alpine landscape of the Wallowas. Soil samples were collected from the Eagle Cap Wilderness Area of the Wallowas at three mountain locations: Eagle Cap, Sacajawea, and Matterhorn. Catenas were studied in the Windblown and Minimum Snowcover zones to examine different pedogenic factors, according to the Synthetic Alpine Slope model. · Field and laboratory testing characterized the alpine soils as predominantly loamy-sands with weak structural development. The 1:1 water pH values range from 6.5 to 7.3, and the soil hues are lOYR and 2. SY in color. Soil classification characterized Eagle Cap soils as Andisols: Lithic and Typic Haplocryands. The Matterhorn and Sacajawea residuum was not classified. Parent material influence on soil development was more noticeable on granodiorite than basalt, reflecting the propensity of granodiorite to weather rapidly. Marble and shale sites lacked soil development. All the soils exhibited eolian influence, determined from silt mineralogy results. While this component did not dominate the soils as in other alpine areas, its presence was ·proven by quartz and feldspars in soils developed on marble and calcite in soils developed on granodiorite. Sodium fluoride (NaF) pH tests indicate that there is also a high aluminum content in the alpine soils, probably due to influx of Mazama volcanic ash. Krummholz and alpine turf increase the organic content of the soil, although soils beneath krummholz were not as deep. This is partially due to decreased snowcover, subsequent lack of moisture, and different parent material. All soils show a decrease in organic carbon with depth indicating that bioturbation was either low, or the soil recovered from the disturbance rapidly. Organocutans found on the bottom of rocks in the B horizon illustrate organic trans location. The increase in pH with depth shows the influence of surficial organic matter, translocated dusts, and ash. Nunatak and landmass influence on soil development was undetermined.

Orientador: Thiago Sanna Freire Silva / Resumo: Os sistemas montanhosos são laboratórios naturais para análise de gradientes. Elevação, amplitude e diferenças topográficas em montanhas podem criar fortes diferenças microclimáticas a curtas distâncias, aninhadas dentro da mesma região biogeográfica e macroclimática, permitindo-nos compreender melhor as respostas da vegetação e os feedbacks sobre a disponibilidade de água. Neste estudo, avaliamos como a distribuição da vegetação está ligada à disponibilidade de água na Serra do Espinhaço. Para tanto, abordamos as seguintes questões: 1) Quais são os regimes hidroclimáticos encontrados na Serra do Espinhaço e seus correspondentes tipos de vegetação? 2) Onde a produtividade da vegetação é mais e / ou menos acoplada aos regimes hidroclimáticos? 3) A topografia é capaz de impactar a produtividade da vegetação e suas relações de acoplamento com regimes hidroclimáticos? Além disso, considerando estas relações ambientais e de vegetação, 4) Como a resiliência climática dos tipos de vegetação nesta região varia? Conclui-se que na faixa do Espinhaço, a maior parte da dinâmica de produtividade da vegetação espaço-temporal é impulsionada por condições hidroclimáticas e / ou topo-edáficas. Nossos resultados mostram que a vegetação da Caatinga teve uma resposta plástica e relativamente rápida ao Déficit Hídrico Climático (CWD) e foi o tipo de vegetação com maior restrição hídrica. Cerrado e Campos Rupestres tiveram respostas semelhantes às flutuações no déficit hídrico, mostrando um gradie...

Elevation, amplitude and topographical differences over mountains can create strong microclimatic differences over short distances, nested within the same biogeographic and macro-climatic region, thus allowing us to better understand vegetation responses and feedbacks to water availability. In this study, we assessed how vegetation distribution is linked to water availability in the Espinhaço Mountain Range. For that, we addressed the following questions: 1) Which are the hydroclimatic regimes found in the Espinhaço Range and their corresponding vegetation types? 2) Where does vegetation productivity is more and/or less coupled to hydroclimatic regimes? 3) Is topography able to impact vegetation productivity and its coupling relations to hydroclimatic regimes? Also, considering these environmental and vegetation relationships, 4) How does the climatic resilience of the vegetation types in this region vary? We conclude that in the Espinhaço Range, most of the spatio-temporal vegetation productivity dynamics are driven by hydroclimatic and/or topo-edaphic conditions. Our results show that “Caatinga” vegetation had a plastic and relatively fast response to Climatic Water Deficit (CWD) and was the most water-constrained vegetation type. “Cerrado” and “Campos Rupestres” had similar responses to fluctuations in water deficit, showing a gradient of slower to faster responses from “Humid” to “Very dry” hydroclimatic regi...

This study was designed to observe the effects of selenium from plant material in sheep after a single, oral dose. Purified sodium selenite and selenomethionine were given as positive controls. The plant Symphyotrichum spathulatum (Western Mountain Aster) was collected, analyzed for selenium content, and administered orally to sheep at varying doses according to body weight. Clinical signs were observed for 7 days during which time whole blood, serum, and expired air were collected. Following euthanasia, tissues were collected for histopathological analysis and mineral analysis. Clinical signs were less apparent than expected and included depression and mild dyspnea in sheep receiving the highest doses of selenium as plant material, whereas pathologic lesions were prominent. Acute myocardial degeneration and necrosis was most severe in the highest dose animals, but present to lesser degrees as dose decreased. Pulmonary lesions of edema and congestion were less frequently observed. Thirteen animals died prior to study completion. Selenium concentration in tissues, brain, liver, kidney cortex, atrium, ventricle, and skeletal muscle, increased with increasing dose of plant material. Treatment had a significant impact on selenium concentration in all tissues collected for mineral analysis (P < 0.01). Whole blood and serum were collected to study the toxicokinetics of selenium in these sheep. Serum kinetic parameters that increased significantly with increasing dose included the elimination rate constant, peak selenium concentration, and area under the selenium concentration versus time curve. Serum kinetic parameters that significantly decreased with increasing dose included the absorption and elimination half-lives. Whole blood kinetic parameters that increased significantly with increasing dose included the elimination rate constant, peak selenium concentration, and area under the curve. Expired air was collected to study the respiratory toxicokinetics of selenium in the sheep. The selenium concentration in expired air from sheep receiving selenomethionine was significantly greater than all other treatments (P < 0.0001) at all collection time points. But an intriguing finding was the dramatic differences in elimination profile curves as selenium dose increased with the plant material. The highest dose group elimination curve continually increased through all collection time points. All other groups dosed with plant material saw a decrease in selenium elimination by the last collection time point.

The Prospect Rock Fault (PRF) is key to our understanding of the regional tectonic evolution of Vermont during the Taconic, Salinic, and Acadian Orogenies, and may have played an important role in the exhumation of blueschist and eclogite-facies rocks in the Tillotson Peak Complex (TPC) during the Taconic Orogeny. The TPC is in the footwall of the PRF in the eastern limb of the Green Mountain Anticlinorium. In the TPC, the dominant foliation is S2 and E-W trending F2 folds parallel L2 stretching lineations, which trend orthogonal to regional N-S trending folds associated with the Taconic Orogeny. The PRF itself is folded by F2 folds. Presently, there is a lack of consensus about the role of the PRF in the exhumation of the TPC, and studies have not reconciled the formation of the E-W folds and lineations to a regional model. Oriented samples and structural data were collected from the footwall of the PRF over several transects. Samples were processed into orthogonal thin sections for microstructural analyses and for 40Ar/39Ar step heating of white mica. The dominant foliations in the PRF samples were identified through microstructural analysis and correlating the age of deformation as S2 and S3. These were defined in thin section by mica and quartz microlithons, and oriented mica grains. S1, and in some samples S2, are locally preserved in some mica domains and albite/garnet inclusion trails. S4 appears as crenulations of S3, with no significant new mineral crystallization. In the field, L2 and L3 lineations are defined by mineral and quartz rods, and L4 lineations are defined as intersection lineations on S2 surfaces. 40Ar/39Ar analyses yielded plateau ages ranging from 458.6 ± 2.0 Ma to 419.0 ± 2.4 Ma (1σ). The oldest plateau ages are just slightly younger, yet concordant, with published and new 40Ar/39Ar ages from the TPC and come from the structurally highest portions of the footwall in the northern part of the study area. Virtually all apparent age spectra show age gradients. Results from this study suggest the PRF played a role in exhumation of the TPC and ages obtained are closely aligned with deformation ages constrained from 40Ar/39Ar dating in southern Quebec for the Taconic D2 and Salinian D3 deformation. These dates may aid correlatation of ages and structures regionally and further refining of tectonostratigraphic models describing southern Quebec and New England.
