Research Support

(Principal investigator) Dortch, J.M., Rates, magnitudes, and timing of Quaternary landscape evolution across an asymmetric, semi-arid high mountain range: the Ladakh Range, northwest Himalaya., University Research Counsel.. $3000. Funded 2008

(Principal investigator) Dortch, J.M., Owen, L.A., Dietsch, C., Caffee, M.W., The goal of this study is to test the hypothesis that widespread glaciation across the northern side of semi-arid Ladakh Range, located in the northwest Himalaya in northern India, and limited glaciation across its southern side produced a strong gradient in glacial erosion across the Range, and induced differential landscape evolution., Sigma Xi student research grant.. $1000. Funded 2008

(Principal investigator) Dortch, J.M., Owen, L.A., Dietsch, C., Caffee, M.W., The goal of this proposed study is to test the hypothesis that more extensive glaciation across the northern side of the Ladakh Range produced a strong gradient in glacial erosion across and induced faster uplift rates and more high peaks >23,000 ft above seal level on the northern side of the mountain surface., American Alpine Club. . $500. Funded 2008

(Principal investigator) Dortch, J.M., Owen, L.A., Caffee, M.W., Terrestrial cosmogenic dating of the Wonder Lake moraines, McKinley River Basin: in pursuit of understanding the nature of glaciation and climate change in the Denali National Park., Muri learning and Science Grant.. $3260. Funded 2007

Dortch, J.M., Grant awarded to a graduate student investigating Holocene climate change. , Michael McPhaden Award.. $1000. Funded 2007

(Principal investigator) Dortch, J.M., Owen, L.A., Caffee, M.W., Quantifying the timing and extent of glaciation on the northern slopes of the Alaska Range in order to understand paleoclimatic fluctuations., American Alpine Club.. $500. Funded 2006
