Repeating historical photos of glaciers
The Project
Global climate change is having profound impacts on mountain  environments. In order to understand how a changing climate will affect  alpine ecosystems and water resources in the future, it is critical to  document their current status. The goal of this project is to implement a  consistent system for recording the condition of glaciers and alpine  ecosystems in North and South America. Through a unique combination of  repeat photography and crowd-sourced citizen science, we aim to engage  alpine enthusiasts in documenting changes in the Sierra Nevada and Andes  mountain ranges, provide high resolution data to climate scientists,  and build public awareness through compelling images and media.  
How Can You Participate?
Anyone can participate and contribute to this project by visiting these  locations following GPS coordinates, lining up the historic photo,  taking a photograph, and sending it to us. Most of these locations area  easily accessible and often hundreds of people pass right by these  photopoints every year, but many cases these photos have only been  repeated once or twice. If you are feeling more adventurous,  there are hundreds more photo locations we have not identified. 
How will this data be used?
The Alpine of the Americas Project is working closely with the Glaciers of the American West project to add to their database of glaciers from the  Sierra Nevada.  In the Andes they are working with researchers at a government research agency in Mendoza.  They have been tasked  with completing an inventory of all glaciers in the Argentine Andes in  the next four years; a massive project in which repeat photography is a  very useful tool.  As the Alpine of the Americas Project cultivates more contacts with climate  researchers they hope to expand to other mountain ranges.
