I have compiled a collection of 28 glacier repeat photographs in the Sierra Nevada. Entitled " High Sierra Glacier Change, A Collection of Repeat Photography: 1883 - 2008 ", the collection contains historical and repeat photographs collected during my thesis work and thereafter. The collection can be viewed here (PDF, 15 mb): I began working on this project in January when time allowed for me to begin pairing photos that I had taken in 2004! The collection is still a work in progress and I welcome any feedback or suggestions.
