Investigation: When will there no longer be glaciers in Glacier National Park?
This activity was selected for the On the Cutting Edge Exemplary Teaching Collection
Resources in this top level collection a) must have scored Exemplary or Very Good in all five review categories, and must also rate as “Exemplary” in at least three of the five categories. The five categories included in the peer review process are
- Scientific Accuracy
- Alignment of Learning Goals, Activities, and Assessments
- Pedagogic Effectiveness
- Robustness (usability and dependability of all components)
- Completeness of the ActivitySheet web page
For more information about the peer review process itself, please see http://serc.carleton.edu/NAGTWorkshops/review.html.

In this activity, students use historical data on the extent of the Grinnell Glacier in Glacier National Park to estimate when the glacier will melt completely.
- Build skills and gain experience in analyzing and interpreting real geologic data
Context for Use
This activity is meant to follow a discussion of glaciers and their effects on alpine landscapes.
Teaching Notes and Tips
For more recent data on the Grinnell Glacier, students can use Google Earth imagery, USGS repeat photographs, or images from the Glaciers of the American West. Integrating data from various sources and deriving quantitative data from imagery can add to the skills students will develop in this exercise.
This exercise also requires glacier imagery, and several sources of imagery are provided in the references section.
The activity report can be completed individually or as a group and should be a summary of the Investigation Question, the process for answering it and what that answer was. The report should be concise (less than 2 pages, typed) and should answer each of the major questions asked in the activity sheet.
