Grinnell Glacier from Elrod's Rock
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.
Grinnell Glacier from South Moraine
This pair of photographs from Grinnell Glacier’s southeast edge shows the dramatic change in the glacier’s volume and area. Note the glacier’s depth along the headwall and its extent at the terminal moraine in the historic photograph.
Grinnell Glacier from partial North Moraine
North moraine of Grinnell Glacier. In 1924 the glacier’s ice margin was still in proximity to its lateral moraine .

Grinnell Glacier from footbridge 1887-2008
Among the earliest photos of Grinnell Glacier, this 1887 image shows the immense extent and depth of the glacier at the turn of the 20th century.
