John Garver, professor of geology, is co-author (with P.R. Reiners, Lydia Walker '04, former Union colleague Joan Ramage, and Stephanie Perry '04) of a paper, “Implications for timing of Andean uplift based on thermal resetting of radiation-damaged zircon in the Cordillera Huayhuash, northern PerĂº” in Journal of Geology, (2005, v. 113, n. 2, p. 117-138.) The paper details how the Andes have been uplifted and grown in the last 10 million years. The main implication is that the uplift and high topography in this part of the Andes is less than 6 million years old, which is young geologically. The paper focuses on the uplifted area that includes Nevado Yerupaja, the 21,000-foot peak made famous in “Touching the Void” a book and film by Joe Simpson about an epic climbing adventure. The paper was based largely on the senior thesis work of Walker and Perry. Walker has joined Peace Corps to work on reforestation and conservation projects in Guatemala. Perry is pursuing her master's degree at the University at Albany with a thesis about the timing of the formation of the St. Elias Mountains in Alaska, in collaboration with Garver.
