Rock Glaciers Of The Beartooth And Northern Absaroka Ranges, Montana, Usa, Zachary M. Seligman, Anna E. Klene, Frederick E. Nelson Sep 2019

Rock Glaciers Of The Beartooth And Northern Absaroka Ranges, Montana, Usa, Zachary M. Seligman, Anna E. Klene, Frederick E. Nelson

Six hundred sixty‐one rock glaciers in the northern Absaroka and Beartooth Ranges of south‐central Montana were digitized and evaluated using geographic information systems technology and an array of topographic and environmental parameters. Beartooth rock glaciers are larger, occur at higher elevations, receive more precipitation, and are subject to lower temperatures than northern Absaroka rock glaciers. Elevation is strongly correlated with rock glacier activity. Comparative analysis of these adjacent mountain ranges indicates that Beartooth geomorphic landscapes are shifting from predominantly glacial to periglacial regimes, and that the northern Absarokas have largely completed this transition. Because glaciers are declining in response to …


Perceptions Of Vulnerability To Flooding, Hurricanes, And Climate Change On Grand Isle, Louisiana’S Only Inhabited Barrier Island, Lauren Miller Jan 2019

Perceptions Of Vulnerability To Flooding, Hurricanes, And Climate Change On Grand Isle, Louisiana’S Only Inhabited Barrier Island, Lauren Miller

Graduate Student Theses, Dissertations, & Professional Papers

This study used in-depth interviews of permanent residents on Grand Isle, Louisiana, a remote barrier island, to better understand their perceptions of structural flood measures, non-structural responses to flooding and hurricanes, and perceptions of vulnerability to flooding, hurricanes, and climate change on a remote barrier island-Grand Isle, Louisiana. Residents' perceptions regarding the various structural measures implemented by the federal, state, and local government appeared mixed. Non-structural responses to flooding risks implemented at the household, community, state, and federal level continue to strengthen resiliency on Grand Isle. According to interviewees, aspects of environmental, rural, and economic vulnerability on Grand Isle impact …


Just Open A Window: Understanding The Vulnerability To Summer Heat Of A Mountain Community In The Western United States, Missoula, Mt, Julie J. Tompkins Jan 2018

Just Open A Window: Understanding The Vulnerability To Summer Heat Of A Mountain Community In The Western United States, Missoula, Mt, Julie J. Tompkins

Graduate Student Theses, Dissertations, & Professional Papers

How do we conceptualize vulnerability or resiliency to a natural hazard when it has not historically been understood as such? This study focuses on Missoula, located in mountains of western Montana, which has steadily grown by 1-2% per year to almost 75,000 residents. The formerly temperate quality of its winters and summers has also been changing. Projections from the 2017 Montana Climate Assessment estimate the state will experience a 2-5°F increase in mean annual air temperature over the next two decades, prompting city and county officials to plan for scenarios not formerly in their consideration. Of further concern is the …
