The photo below was taken in 1981 from the summit of Mt. Gould in Glacier National Park. The remnants of Grinnell Glacier are shown in the bottom portion of the photo with bands of debris covering the ice.
Icebergs dot the lake which has formed as the glacier melted.
The aerial photograph below, taken from specially-equipped planes late in the summer, is a valuable tool for tracking glacier changes. This photograph has been scanned into a computer. We superimposed red lines to indicate the margins of Grinnell Glacier during different times of its retreat. The glacier covered approximately 576 acres in 1850. Additional shrinkage has occurred since 1993.
