Investigation: When will there no longer be glaciers in Glacier National Park?

An Investigation Question activity developed by Carol Ormand, Wittenberg University.

Summary

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.

Learning Goals

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.

Teaching Materials

Student handout for Grinnell Glacier investigation (Microsoft Word 31kB Mar17 04)
This exercise also requires glacier imagery, and several sources of imagery are provided in the references section.

Assessment

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.
