Essential Lens: Analyzing Photographs Across the Curriculum

Earth, Climate, and Change: Observing Human Impact #3504 Muir Glacier and Muir Inlet, 2003


Date: September 1, 2003
Location: Alaska
Photographer: Bruce Molnia
Source: U.S. Geological Survey


This photo was taken in September 2003. In the 23 years between photographs, Muir Glacier has retreated more than a mile and ceased to have a tidewater terminus. Since 1980, Muir Glacier has thinned by more than 600 ft, permitting a view of a mountain with a summit elevation of greater than 4000 ft, located in the center of the photograph. A re-examination of the 1980 photograph shows that the summit of this mountain was visible but that it blended in with adjacent clouds.
