The Glacier RePhoto Project
This project seeks to summarize the existing glacier repeat photographic record throughout the American West. The objectives are to organize historical repeat photographs, their locations, and photographic attributes into a database and acquire new repeat photographs. In collaboration with the Glaciers of the American West project, this project will assist in quantifying the rate and magnitude of glacier change and communicate the changes to scientists and to the public. This work builds on my glacier repeat photography in the Sierra Nevada, California. The focus for 2012 was on the Glacier-clad Volcanoes of the Cascade Range, California - Washington.

Glacier Change in the Sierra Nevada, California
My research on how glaciers in Sierra Nevada, California, have retreated over the 20th century. I collected field data in 2003 and 2004, and have continued to visit selected sites to capture repeat photographs (2006, 2007, 2008, 2011). My current plans for this project are to revisit my study sites in 2013 and 2014. Below are links to my thesis, webpage, and reports.
