David Harbor, Jeffrey Rahl Present Findings at Geology Meeting
David Harbor, professor of geology, and Jeffrey Rahl, assistant professor of geology, both of Washington and Lee, presented the results of their summer research to approximately 6,000 geoscientists at the annual meeting of the Geological Society of America in October.
Their work was supported by the Lenfest program and two alumni funds in the geology department, and took them to northwestern Argentina for a second year. There, they extended their collection of samples of the region back in geologic time in order to establish reliable records of its geologic history and test the relative influence of tectonic, climatic and geomorphic processes on the erosion of orogenic plateaus.
Accompanied by students Ryan Hartman ’12 and Doug Sberna ’13, they also used a differential GPS system and laser surveying tools to create a detailed profile of a river channel and mapped the distribution of sediments and bedrock exposed in the modern river valley.
