Abstract:
Grasshopper Glacier is a cirque glacier in the central Rocky Mountains of the United States. It is a remnant of the “Little Ice Age”, rather than the more widespread and older Pinedale Glaciation. The glacier has not been monitored on a regular basis and very few maps have been published of the area, but it has been studied, photographed, occasionally mapped, and described by scientific and non-scientific groups, at different times since 1898. These photographic, cartographic, and written records make it possible to trace the fluctuations of this glacier since 1898. Grasshopper Glacier has had periods of positive mass balance, but the overall trend has been negative, with accelerated melting in recent years. It is estimated that Grasshopper Glacier has lost about 50% of its area and as much as 90% of its volume, since 1898. Other Rocky Mountain glaciers are experiencing similar wastage and, if current conditions continue, these glaciers will disappear by the middle of the next century.

Abstract:
Moraines of two different age groups have been identified fronting the present-day glaciers and snowfields in Glacier National Park, Montana. The subdued, vegetated moraines of the older group have been found at 25 sites, mainly in the central part of the Lewis Range. These older moraines are in places overlain by the Mazama ash. Although the exact age of the moraines has not been determined by radiocarbon dating, vegetative evidence and correlation with other pre-altithermal age moraines in the Rocky Mountains suggest that these older moraines date from 10 000 BP or earlier. Whether these moraines are the product of a separate advance after the end of the Wisconsin glaciation or are simply the product of the last advance or stillstand of Wisconsin glaciers before final deglaciation is not known.Moraines of the younger group, consisting of fresh bouldery rubble, are common throughout Glacier Park. Tree-ring analyses indicate that some of these younger moraines were deposited by advances that culminated during the mid-19th century. At that time there were more than 150 glaciers in Glacier Park. This episode of mid-19th century climatic cooling resulted in the most extensive glacial advance in this region since the end of the Wisconsin glaciation.Present-day glaciers have shrunk drastically from their mid-19th century positions; more than half the glaciers present during that time no longer exist. Much of this retreat occurred between 1920 and the mid-1940's, corresponding to a period of above-average summer temperatures and below-average annual precipitation in this region. Between 1966 and 1979, several of the larger glaciers in the Mount Jackson area of Glacier Park advanced as much as 100 m.

Abstract:
AbstractRock glaciers are periglacial alpine landforms that are found in many locations worldwide. Whereas well-developed models of deformation are established for traditional alpine glaciers, rock glacier deformation is poorly understood. Geophysical data from Lone Peak Rock Glacier (LPRG), southwest Montana, USA, are paired with lidar bare-earth 1 m digital elevation model (DEM) analysis to explore potential genetic relationships between internal composition, structure and regularly spaced arcuate transverse ridges expressed at the rock glacier surface. The internal composition of LPRG is heterogeneous, with frozen debris and clean ice overlain by an unconsolidated talus mantle. Upslope-dipping, clearly distinguished reflectors in the ground-penetrating radar (GPR) longitudinal survey at LPRG correspond to transverse ridges. The spacing and slope of individual features at the surface and in the subsurface were measured and compared and are found to be similar. The structures observed at LPRG and other rock glaciers are similar to structures detected in glaciotectonically altered sediment, ice-cored moraines and other rock glacier settings. This finding suggests that transverse ridges on rock glaciers may be used as geomorphic indicators of internal deformation. This study contributes to the body of research on the application of GPR to rock glaciers, and is the first to directly pair and analyze individual surface topographic features with internal structures.

Abstract. In this study we present the Portland State University Active Rock Glacier Inventory (n=10 332) for the contiguous United States, derived from the manual classification of remote sensing imagery (Johnson, 2020; https://doi.org/10.1594/PANGAEA.918585). Individually, these active rock glaciers are found across widely disparate montane environments, but their overall distribution unambiguously favors relatively high, arid mountain ranges with sparse vegetation. While at least one active rock glacier is identified in each of the 11 westernmost states, nearly 88 % are found in just five states: Colorado (n=3889), Montana (n=1813), Idaho (n=1689), Wyoming (n=839), and Utah (n=834). Mean active rock glacier area is estimated at 0.10 km2, with cumulative active rock glacier area totaling 1004.05 km2. Active rock glaciers are assigned to a three-tier classification system based on area thresholds and surface characteristics known to correlate with downslope movement. Class 1 features (n=7042, average area = 0.12 km2) appear to be highly active, Class 2 features (n=2415, average area = 0.05 km2) appear to be intermediately active, and Class 3 features (n=875, average area = 0.04 km2) appear to be minimally active. This geospatial inventory will allow past active rock glacier research findings to be spatially extrapolated, help facilitate further active rock glacier research by identifying field study sites, and serve as a valuable training set for the development of automated rock glacier identification and classification methods applicable to other large regional studies.

Abstract. Glacier mass balance measurements help to provide an understanding of the behavior of glaciers and their response to local and regional climate. In 2005 the United States Geological Survey established a surface mass balance monitoring program on Sperry Glacier, Montana, USA. This project is the first quantitative study of mass changes of a glacier in the US northern Rocky Mountains and continues to the present. The following paper describes the methods used during the first 11 years of measurements and reports the associated results. From 2005 to 2015, Sperry Glacier had a cumulative mean mass balance loss of 4.37 m w.e. (water equivalent). The mean winter, summer, and annual glacier-wide mass balances were 2.92, −3.41, and −0.40 m w.e. yr−1 respectively. We derive these cumulative and mean results from an expansive data set of snow depth, snow density, and ablation measurements taken at selected points on the glacier. These data allow for the determination of mass balance point values and a time series of seasonal and annual glacier-wide mass balances for all 11 measurement years. We also provide measurements of glacier extent and accumulation areas for select years. All data have been submitted to the World Glacier Monitoring Service and are available at doi:10.5904/wgms-fog-2016-08. This foundational work provides valuable insight about Sperry Glacier and supplies additional data to the worldwide record of glaciers measured using the glaciological method. Future research will focus on the processes that control accumulation and ablation patterns across the glacier. Also we plan to examine the uncertainties related to our methods and eventually quantify a more robust estimate of error associated with our results.

Abstract:
In 1925, then-Captain AW Stevens of the US Army Air Corps took low-angle, oblique aerial photographs of the spectacular landscape of Glacier National Park, Montana (USA). Two of those photographs, of astonishing clarity, were used in a US Geological Survey Professional Paper published in 1959, but were subsequently assigned to the US National Archives and never utilized again. This paper advocates the usefulness of Stevens’ photographs for documenting landscape change from the early 20th century to the present. Stevens’ photographs illustrate the “state” of numerous Park glaciers in 1925, and are the first known aerial photographs of the Park glaciers. These photographs can be used in comparison to modern photographs to illustrate the extent of glacial recession that has occurred in the Park since 1925.

Abstract:
Abstract The late Pleistocene Big Timber glacier of west-central Montana was used as the test case for a model which calculates the mass balance of a paleoglacier using glacial flow theory. Application of Glen’s flow law to a detailed reconstruction of the glacier provided an estimate of the component of mass flux due to internal deformation. Assuming basal slip to be zero where mass flux due to deformation was a maximum, the mass flux at the equilibrium-line altitude (ELA) an ablation gradient of 3.0 ± 0.6 mm/m, and an accumulation gradient of 1.0 ± 0.2 mm/m were determined. Application of the continuity model above and below the ELA generated a second estimate of mass flux at discrete points along the glacier. The difference between deformation flux and continuity flux yields a first approximation of slip, which is highly variable along the glacier. Since the mass-balance gradients are climatically controlled, this model provides information on the paleoclimatic setting of the glacier. The low gradients indicate that, during the last glacial maximum, the east side of the central Rocky Mountains experienced a cold, dry environment much like that of modern-day glaciers in the Brooks Range of Alaska.

Abstract:
Glacier National Park, in northwestern Montana, is a unique and awe-inspiring national treasure that is often used by the media and public-at-large as a window into the effects of climate change. An updated inventory of glaciers and perennial snowfields (G&PS) in the Park, along with an assessment of their change over time, is essential to understanding the role that glaciers are playing in the environment of this Park. Nine inventories between 1966 and 2015 were compiled to assess area changes of G&PS. Over that 49-year period, total area changed by nearly -34 ± 11% between 1966 and 2015. Volume change, determined from changes in surface topography for nine glaciers, totaling 8.61 km² in area, was +0.142 ± 0.02 km³, a specific volume loss of -16.3 ± 2.5m. Extrapolating to all G&PS in the Park in 1966 yields a park-wide loss of -0.660 ± 0.099 km³. G&PS have been receding in the Park due to warming air temperatures rather than changes in precipitation, which has not changed significantly. Since 1900, air temperatures in Glacier National Park have warmed by +1.3 C°, compared to +0.9 C° globally. Spatially, G&PS at lower elevations and on steeper slopes lost relatively more area than other G&PS.

Abstract:
Avalanche paths are unique ecosystems that represent a significant portion of the landscape in the northern Rocky Mountains. Frequent avalanche disturbance results in vegetative cover that is unlike the adjacent coniferous forest. These high relief environments have the potential to remove carbon from the atmosphere at rates differing from those of the surrounding forest, and to regulate matter and/or energy fluxes to downslope ecosystems. This thesis attempts to estimate organic carbon on south-facing avalanche paths in the southern portion of Glacier National Park, Montana. I am specifically interested in total organic carbon density, compartmental carbon density, and change in organic carbon over time as a function of shrub and tree diameter. Using an integrated sampling method, estimates of total organic carbon on avalanche paths appear to be different than those of the adjacent forest and similar to those of other shrub formation types in the area. However, the potentially moveable litter compartment is consistently larger. Organic carbon from shrub and trees growing on paths appears to be increasing at a continuous rate leading up to disturbance, while a typical individual's rate of increase appears to be slowing. The organic material temporarily stored on avalanche paths could serve as an important outside carbon source for near and distant aquatic ecosystems.

Abstract:
Glacier retreat is considered a clear sign of global climate change. Although a rich body of work has documented glacial response to climate warming trends, comparatively little research has assessed vegetation change in recently deglaciated areas. In this study, we assess vegetation change at two glacier forefronts in Glacier National Park, Montana, through remote sensing analysis, fieldwork validation, and statistical modelling. The research objectives were to: 1) quantify the spatial and temporal patterns of landcover change of five classes"ice, rock, tree, shrub, and herbaceous at the two glacier forefronts in Glacier National Park, and 2) determine the role of selected biophysical terrain factors (elevation, slope, aspect, solar radiation, flow accumulation, TWI, and geology) on vegetation change at the deglaciated areas. Landsat imagery of the study locations in 1991, 2003, and 2015 were classified and validated using ground truth points and visual interpretation for accuracy. Overall accuracies were above 75% for all classified images. To identify biophysical correlates of change, we used generalized linear mixed models with non-vegetated surfaces to vegetation (code=1) or stable non-vegetation class (code=0) as a binary response variable. Results revealed elevation, slope, TWI, geology, and aspect to be associated with increased vegetation over time at Jackson Glacier forefront, whereas elevation, slope, solar radiation, and geology were significant at Grinnell Glacier forefront. New case studies on vegetation change in recently deglaciated regions can deepen our knowledge about how glacier retreat at local scales results in recharged ecosystem dynamics.

Glacier retreat is considered a clear sign of global climate change. Although glaciers are retreating globally, comparatively little research has assessed how vegetation changes in recently deglaciated areas. The research objectives were to: 1) quantify patterns of landcover change of five classes—ice, rock, tree, shrub, and herbaceous at two glacier forefronts in Glacier National Park, and 2) determine the environmental and terrain factors that affect vegetation change at the deglaciated areas. Landsat imagery of the study locations in 1991, 2003, and 2015 were classified and validated using ground truth points and visual interpretation for accuracy. To identify terrain and environmental factors that influence change, we modeled change from nonvegetated surfaces to vegetation (code=1) and the stable non-vegetation class (code=0). Results revealed elevation, slope, topographic moisture, geology, and aspect to be associated with increased vegetation over time at Jackson Glacier forefront. Elevation, slope, solar radiation, and geology were significant at Grinnell Glacier forefront, indicating some geographic differences in important factors. New case studies on vegetation change in recently deglaciated regions can deepen our knowledge about how glacier retreat at local scales results in recharged ecosystem dynamics. This study provides further insight on the future of alpine ecosystems as they respond to global climate change and a compelling new perspective on the future of the Park. Additionally, we demonstrate the benefits of using remote sensing applications to study land cover change as a proxy for vegetation colonization, especially in remote mountainous environments.

Abstract:
Les glaciers Andins présentent des taux de recul parmi les plus importants au monde, et contribuent à la hausse du niveau des mers. Ils constituent aussi des ressources en eau vitales pour les vastes zones semi-arides le long de la Cordillère des Andes (10°N-56°S), en alimentant les rivières lors des sécheresses. En dépit du retrait des glaciers Andins, les mesures directes des fluctuations glaciaires sont éparses, de court terme, incomplètes, et ne permettent donc pas une estimation précise de la perte de glace récente à l'échelle de la chaîne entière. Décrire quantitativement cette perte à différentes échelles spatio-temporelle est cruciale afin de mieux anticiper les impacts écologiques, économiques et sociaux. Premièrement, nous avons évalué la performance d'une méthode visant à calculer les changements de masse des glaciers Andins. Cette méthode utilise les séries temporelles des modèles numériques de terrain (DEM) produit par des images stéréoscopiques Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER). Sur la zone de validation de la méthode, le Champ de Glace Nord de Patagonie (NPI), nous avons observé un bilan de masse fortement négatif de -1.06 ± 0.14 m w.e. a-1 pour la période 2000-2012. Ces résultats sont cohérent avec les estimations faites précédemment, mais aussi avec une seconde estimation (-1.02 ± 0.21 m w.e. a-1) obtenue indépendamment par différentiation de DEMs de meilleur résolution, Shuttle Radar Topography Mission (SRTM) et Satellite pour l'Observation de la Terre 5 (SPOT5). Ce travail nous a permis de (i) valider la méthode appelée " ASTER monitoring Ice towards eXtinction " (ASTERIX) sur la totalité des Andes, (ii) confirmer l'absence de pénétration du signal radar SRTM dans la bande C sur la neige du NPI (sauf pour une petite région au dessus de 2900 m a.s.l) avec des effets négligeables sur le bilan de masse du NPI; et enfin (iii) fournir la base de travail pour une analyse des variations du bilan de masse du NPI durant différentes sous périodes entre 1975 et 2016, grâce à des DEMs supplémentaires. Ensuite, nous avons généré plus de 30000 DEMs ASTER afin de calculer la perte de l'intégralité des glaciers Andins, et ce pour les deux dernières décennies. La perte de masse à l'échelle des Andes s'élève ainsi à -22.9 ± 5.9 Gt a-1 (-0.72 ± 0.22 m w.e. a-1) pour la période d'étude entière, ou -26.0 ± 6.0 Gt a-1 en incluant les pertes subaquatiques. Toutes les régions affichent une diminution du volume de glace. Les taux les plus négatifs sont observés dans les Andes Patagoniennes (-0.78 ± 0.25 m w.e. a-1) et dans les Andes Tropicales (-0.42 ± 0.24 m w.e. a-1). Les pertes sont modérées dans les régions intermédiaires des Andes Arides (-0.28 ± 0.18 m w.e. a-1). Pour la première fois à l'échelle des Andes, une tendance inter-décennale de la perte volumique a été mise en évidence. Les taux d'amincissement des glaciers tropicaux et ceux situé sous 45°S sont négatifs et stables sur la période considérée. Cependant, alors que les glaciers des Andes arides sont proche de l'équilibre dans les années 2000, leur taux d'amincissement augmentent drastiquement à partir de 2010, coïncident ainsi avec une période de sécheresse intense depuis 2010. L'étude des contributions des pertes de masse décennales des glaciers aux débits des rivières révèle que la fonte de ces glaciers a en partie aidé à minimiser les impacts négatifs de cette sécheresse dans les Andes arides. Les résultats obtenus au cours de cette thèse apportent une meilleure compréhension des pertes récentes des glaciers Andins, localement et régionalement
Andean glaciers are amongst the fastest shrinking and the largest contributors to sea level rise in the world. They also represent crucial water resources in the vast semi-arid portions of this large Andes Cordillera (10°N-56°S), sustaining river runoff during dry periods and buffering the effects of droughts. Despite the widespread shrinkage of these glaciers, direct measurement of glacier fluctuations in the Andes are sparse, short-termed and in many cases incomplete, preventing the accurate quantification of recent ice loss for the entire mountain range. Comprehensively quantifying the magnitude of this loss at different special scales is crucial to better constrain future economical, ecological and social impacts. First, we evaluated the performance of a methodology to calculate glacier mass changes on Andean glaciers using time series of digital elevation models (DEMs) derived from Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) stereo images. Over our validation zone, the Northern Patagonian Icefield, we found strongly negative icefield-wide mass balance rates of -1.06 ± 0.14 m w.e. yr-1 for the period 2000-2012, in good agreement with estimates from earlier studies and with a second independent estimate (-1.02 ± 0.21 m w.e. yr-1) obtained by differencing the better resolved Shuttle Radar Topography Mission (SRTM) DEM with a Satellite pour l'Observation de la Terre 5 (SPOT5) DEM. Importantly, this work permitted us to (i) validate "ASTER monitoring Ice towards eXtinction" (ASTERIX) method over the Andes; (ii) confirm the lack of penetration of the C-band SRTM radar signal into the NPI snow and firn except for a small high altitude region (above 2900 m a.s.l.) with negligible effects on NPI-wide mass balance; and (iii) provide the basis for an analysis of NPI mass balance changes during different sub-periods between 1975 and 2016 using additional DEMs. Then, we processed more than 30000 ASTER DEMs to calculate the integrated volume of ice lost by Andean glaciers during the past two decades. Andes-wide mass loss amounts to -22.9 ± 5.9 Gt yr-1 (-0.72 ± 0.22 m w.e. yr-1) for the entire period (or -26.0 ± 6.0 Gt yr-1 including subaqueous losses). All regions show consistent glacier wastage, with the most negative mass balance rates in the Patagonian Andes (-0.78 ± 0.25 m w.e. yr-1) and Tropical Andes (-0.42 ± 0.24 m w.e. yr-1). Relatively moderate loss (-0.28 ± 0.18 m w.e. yr-1) is measured in the intermediate regions of the Dry Andes. The inter-decadal patterns of glacier mass loss is an important contribution of this work, observed for the first time at an Andes-wide scale. We observe steady thinning rates in the Tropics and south of 45°S. Conversely, glaciers from the Dry Andes were stable during the 2000s, shifting to drastic thinning rates during the 2010s, coinciding with conditions of sustained drought since 2010. The evaluation of the imbalanced glacier contribution to river discharge during these two decades revealed that glaciers partially helped to mitigate the negative impacts of this sustained drought in the Dry Andes. The results obtained in this thesis contribute to the understanding of recent Andean glacier evolution at a local, regional and Andes-wide scale. We provide a high-quality, multi-decadal dataset that will be useful to constrain the diversity of present 21st century Andes-wide mass loss estimates, in the pursuit of the good calibration of glaciological and hydrological models intended to project future glacier changes and to improve water resource management in the Andes

Abstract:
Acquisition and interpretation of 3-D seismic data led DeAngelo and Hardage (2001) to describe the channel system in the south central Cut Bank area in Glacier County, Montana. The presence of a low velocity layer called Bentonite was also discovered in the area with the help of well-logs. Bentonite is a volcanic ash, which lies on both sides of the channel system and is absent within the channel. DeAngelo and Hardage (2001) shot a vertical seismic profiling (VSP) survey at well # 54-8 to analyze the formation structure in depth, since seismic signals around the reservoir area were unclear in the 3-D survey. This research attempts to estimate the attenuation properties of the Bentonite layer in the Cut Bank oil field. VSP data is processed for velocity information and estimation of seismic Q using the spectral ratios method (SRM). The SRM theoretically assumes that the propagating signal is a plane seismic wave traveling vertically from one point to another in a homogeneous model. The amplitudes at the start and end points are known and relate to each other with the attenuation coefficient in a frequency range. The relation between the seismic amplitudes at z distance from each other can be expressed as a linear function of frequency after a few modifications. SRM uses the linearity of the logarithmic ratio of the seismic amplitudes over a frequency range. In theory, ratios plotted against a frequency range must produce a flat line. However, in practice, the logarithmic ratios are expected to draw an approximate line (curve), where some of the data points deviate from the origin of the line. Thus fitting a line to the ratios curve and calculating the slope of this curve are necessary. Slope of the curve relates to the seismic attenuation coefficient and further to the seismic Q. The SRM results suggest that Bentonite may have a Q value as low as 5. This highly attenuative and thin (20 to 40 feet throughout the south central Cut Bank Unit) layer alters seismic signals propagating through it. A thorough analysis of the amplitude spectra suggests that seismic signals dramatically lose their energy when they pass through Bentonite. Low energy content of the signals below the Bentonite layer highlights that the recovery of the seismic energy is less likely despite the presence of multiples, which are known to affect the seismic signals constructively. Therefore, separation of reflected events is a greater challenge for the thin reservoir sand units lying underneath the Bentonite layer. Thus the Bentonite layer in the Cut Bank oil field has to be taken seriously and data processing should be done accordingly for better accuracy.

Tesis para optar al grado de Doctor en Ciencias, Mención Geología
La variabilidad del clima durante el último milenio (A.D 1000 - 2000), permitió que diversos glaciares de montaña a escala global hayan experimentado su máximo crecimiento en térmi- nos de su masa, respecto a actuales condiciones. Las causas climáticas de este crecimiento glaciar se relacionan con La Pequeña Edad de Hielo (PEH; A.D 1500 - 1850). Este periodo de interés paleoclimático global ha sido bien documentado en el hemisferio Norte, contrario al hemisferio Sur.. Más aún, existe un desconocimiento profundo acerca de cómo, mecanismos climáticos que actualmente afectan el clima de regiones como los Andes Mediterráneos de Chile y Argentina (AM; 30-37 S), como El Niño Oscilación del Sur, hayan afectado el balance de masa glaciar y las variaciones temporales de la línea de equilibrio altitudinal (ELA) duran- te dicho intervalo. La PEH es un antónimo a lo que acontece actualmente con los glaciares de montaña, donde en regiones como los AM diversos estudios han identificado un severo retroceso. El balance de masa glaciar (MB) y su ELA está influenciado por los cambios en la temperatura del aire, elevación de la Isoterma de 0C y las precipitaciones. La presente tesis doctoral consta de dos capítulos y un capítulo introductorio. Un primer capítulo exhibe las tendencias de las variables climáticas que actúan directamente sobre el MB, y mencionadas anteriormente. Un segundo capítulo, presenta una modelación de la ELA durante A.D 1500 - 1848 mediante un modelo forzado por tres modelos climáticos globales (GCMs). Se estudió las relaciones entre las variaciones temporales en la Temperatura Superficial del Mar (SST) del Océano Pacífico y la variabilidad temporal de la ELA. La temperatura media se ha in- crementado significativamente durante enero, febrero, marzo, y desde agosto a noviembre, considerando 1969 - 2016. La temperatura mínima, por su parte, se ha incrementado signifi- cativamente durante enero y mayo, mientras que la temperatura máxima, excepto en mayo, julio y septiembre, se ha incrementado significativamente durante 1969 - 2015. La isoterma de 0oC (ISO0) registró un incremento significativo en enero, marzo y anual durante 1858 - 2015. Tendencias en la ISO0 (años 2000 - 2015) exhiben un incremento significativo durante enero, mayo, junio y agosto. La precipitación (pp) de abril a septiembre registró una ne- gativa y significativa tendencia desde 1876, con reducciones significativas durante los meses de mayo, junio y julio. Entre 1981 - 2015, una significativa reducción ha sido registrada en la pp de abril a agosto. La ELA anual durante la PEH registró una elevación de 3775 m. Una menor elevación de la ELA fue identificada durante A.D 1640 - 1670 y 1800 - 1948. Contrariamente, una mayor elevación de la ELA fue identificada durante A.D 1550 - 1575. Propiedades espectrales de la ELA modelada indican significativas señales de entre 2 - 7 años de periodicidad, y también señales decadales a multi decadales. Significativas señales espec- trales fueron también obtenidas con el primer modo de variabilidad de la SST región Niño 3.4. Además, correlaciones significativas fueron obtenidas entre la ELA anual y la SST en la región Pacífico. Se propone que la variabilidad de la SST del océano Pacífico fue el principal modulador de los cambios temporales de la ELA en los AM durante A.D 1500 - 1848.

Abstract:
Instrumental climate records reveal fluctuations in summer moisture anomalies and winter snowpack in Glacier National Park, Montana, on decadal and multidecadal timescales. However, because climate records for the region are limited to the 20th century, studies on the impacts of long-duration variations in climate on physical and ecosystem processes were limited. Therefore, a reconstruction of summer moisture variability (June - August) spanning A.D. 1540-2000 was created from a multi-species network of tree-ring chronologies sampled in Glacier National Park. The reconstruction shows decadal-scale shifts between drought and pluvial events with a pronounced cool/wet period spanning the end of the Little Ice Age (A.D. 1770-1840). The single most exceptional drought event occurred over the 20th century (A.D. 1917-1941) and was associated with the most spatially consistent drought regime throughout the northern Rockies and Pacific Northwest over the past ~500 yrs. Among a wider spatial network of hydroclimatic reconstructions arrayed along a north-south Rocky Mountain transect, trends at Glacier National Park were found to be most similar to those in the Canadian Rockies and the Pacific Northwest. Also, many decadal-scale drought/pluvial events were consistent among all sites along the north-south transect - although magnitude, intensity, and time of onset varied. To investigate climatic drivers related to the Little Ice Age glacial maximum and rapid 20th-century retreat, I explored the impact of north Pacific Basin sea-surface temperature anomalies on low-frequency variations in winter snowpack for the park. Temperature anomalies in the north Pacific basin exhibit tight linkages to variations in snowpack; therefore, I used a tree-ring based reconstruction of north Pacific temperature variability and summer drought as proxies for winter glacial accumulation and summer ablation, respectively, over the past three centuries (A.D. 1700-2000). These records show that the 1850's glacial maximum was likely produced by ~70 yrs of cool/wet summers coupled with high snowpack. Glacial retreat coincided with an extended period (>50 yr) of summer drought and low snowpack culminating in the exceptional events of 1917-1941 when retreat rates exceeded 100 m/yr. This research highlights the difficulty in detecting regional expression of global climate change when 'natural' decadal-scale variations in climate are regionally common.

Abstract:
This thesis is the first to the author's knowledge to conduct a holistic investigation of the physical, chemical and microbial properties of a rock glacier. The Lone Peak Rock Glacier (LPRG) is located in the Madison Range of southwest Montana on Big Sky Resort property. This thesis focuses on three scales of investigation: regional, landform, and micro. Regional-scale analysis assessed the role of geology and topography as factors in determining rock-glacier distribution in SW Montana above 2000m. Rock glaciers across alpine landscapes in southwest Montana are preferentially distributed according to rock type, with more rock glaciers occurring in intrusive, foliated intrusive and metamorphic catchments relative to the areal proportion of these rock types than in extrusive and sedimentary catchments. This preferential distribution according to catchment geology is likely due to the affect that geology has on topography and provision of talus. Landform-scale analysis focuses on internal structure, flow dynamics and surface topography of the LPRG. The relationship between surface topography and subsurface structure is explained by passive roof duplex faulting. This finding has implications for rock-glacier flow dynamics and the development of transverse ridges, a common surface feature of rock glaciers studied worldwide. Micro-scale analysis characterizes microbiological and geochemical properties of rock-glacier ice and evaluates it as a microbial habitat, exploring potential associations between debris content and microbial activity. Amber ice (containing 0.1% debris by weight) appears to be a more suitable microbial environment than debris-poor ice (containing < 0.01% debris). This finding highlights the importance of debris as a potential nutrient and energy source to enhance microbial viability in rock-glacier ice.
