Grinnell Glacier from Elrod's Rock

Science Center Objects

This large boulder was used by Morton Elrod and other scientists as a baseline to measure the retreat of Grinnell Glacier’s terminus. It is now referred to as “Elrod’s Rock,” and the glacier’s terminus is no longer visible from this point.
