Repeat Photography Trunk

Nine information panels with side by side photo comparisons
See how Glacier Park's glaciers are changing!


The Repeat Photo Trunk combines photography with precipitation measurement lessons to teach students about Earth's water and energy cycles and the importance of mountain ice. Images included in this exhibit represent a sampling of the US Geological Survey’s (USGS) Repeat Photography Project in Glacier, which conveys how much the glaciers have melted, indicating a warming climate.

This trunk was made possible from a grant from NASA’s Global Precipitation Measurement Mission. It is designed to get students thinking about measuring precipitation—snow and ice, as well as rain—not just to do it, but why we would want to do it.

Climate Change Resource Guide USB

  • Contains a middle school, 2-week curriculum from Facing the Future about climate change. It also has more repeat photos, podcasts, fact sheets and a resource list to learn more about climate change research in Glacier.


  • Checkout the Teacher Guide for the trunk.
  • How Much Water is in this Snow? This lesson will help students understand how scientists use measurements of mass to calculate water in the snowpack.
  • Rain Gauge Activity Lesson Plan (Global Precipitation Measurement Mission, NASA) Rain Gauge Activity- In this hands-on inquiry-based activity, students face an engineering challenge based on real-world applications. Theyare tasked with developing a tool they can use to measure the amount of rainthat falls each day.
  • Fun with Rainfall Measurements (Colorado State Extension). We've included the CoCoRaHS rain gauge in case you andyour students want to try measuring rain at your school. Visit the: Community,Collaborative, Rain, Hail and Snow Network—volunteers working together to measure precipitation across the nation at the CoCoRaHS website.

Borrowing Instructions

All of Glacier's traveling trunks are free of charge. The Repeat Photography Trunk is handled in partnership with the USGS and can be mailed; shipping charges may apply. To borrow this trunk and/or arrangement shipment please email the USGS.
