Sexton Glacier
Sexton Glacier from bench below Siyeh Pass, Glacier National Park.
Piegan Glacier
Piegan Glacier is one of the few glaciers in Glacier National Park that has not significantly changed since photographed in the 1930s.
Red Eagle Glacier
Although the 2009 photo location does not exactly match the historic photo station, a comparison of relative glacial coverage can still be made. Logan Glacier is in the foreground, while Red Eagle Glacier sits beneath the pyramidal peak that bears the same name. It appears that these two glaciers were joined at the time the historic photo was taken, but recessed into their own basins as time...
Iceberg Glacier circa 1940 - 2008
Iceberg Glacier in Glacier National Park.
Jackson Glacier
At the time this historic photograph was taken in 1911, Blackfoot Glacier encompassed the current Jackson Glacier. By 1939, Blackfoot Glacier's recession had resulted in two distinct glaciers, Jackson and Blackfoot. This photo pair shows glacial recession and successive vegetation growth along Jackson Glacier's terminus.
