Alpine of the Americas Project allows you to document alpine changes near your home, which helps your community understand how their natural resources are changing.

Repeat Historic Photographs

Be the first to repeat one of hundreds of historic photographs we have in our database. Go to “Repeat a Photograph” to find resources and learn how you can contribute repeat historic photographs to climate science databases.


Adult & School Trips

Our custom trips give you the opportunity to have a guided experience to repeat historic photographs in California’s Sierra Nevada. Use this opportunity to explore your watershed, document climate disruption, and begin to make positive impact with us today.

Are you a scientist? Are you looking for ways to collect data in remote alpine areas in the Americas?  Could you use observations that are simple and repeatable?  Contact us. We’re eager to understand your needs and how our participants can be useful for your research.

Support our future! Do you believe in our mission?  We do.  Our first two trips have been generously supported through the Matthew Baxter III and the Bishop-Marcus Awards from NatureBridge.  The adventure continues, we are making our process available to all citizens who care about mountains, people, and water.  Please donate now.

Give us feedback! As a collaborative crowd-sourced project, we welcome your input!
