Swiftcurrent Glacier 1911 - 2013
Swiftcurrent Glacier 1911 - 2013.
Thunderbird Glacier
Thunderbird Glacier, Glacier National Park.
Vegetation - Hidden Lake (a)
Vegetation ingrowth on the penninsula and surrounding lakeshore are evident in this pair of photos.
Vegetation - Piegan Glacier
These photographs document another aspect of Glacier Park’s dynamic environment, vegetation change. Although Piegan Glacier has not melted noticeably, years of fire suppression and changing climate may have allowed the invasion of conifers in what was an open meadow in the foreground of the 1930 photo. Also, the demise of the ecologically important whitebark pine (Pinus albicaulis ) is visually...
Vegetation - Sperry Glacier
This view of the northeast portion of Sperry Glacier shows evidence of the glacier's recession as well as the advancement of conifer species and other vegetation on the glacial moraines.
Vegetation - Hidden Lake (b)
Alpine regions along the shores of Hidden Lake (1943 m) show tremendous expansion of vegetation in this photo comparison, especially at the base of Bearhat Mountain.
Sperry Glacier Mid View
Repeating Elrod’s photograph from the same photo point was impossible since he shot from the elevated perspective of the glacier’s surface. The terminus of the glacier has retreated beyond the field of view, but these images give a sense of the glacier’s extent and mass early in the 20th century.
Sperry Glacier from Comeau Pass
The expanse of Sperry Glacier that once greeted hikers facing NE on Comeau Pass is in stark contrast to the bedrock and vegetation that has since emerged as the ice retreated. The Marble image, most likely taken in the 1920s or early 1930s, was featured on a postcard with this caption: " Sperry Glacier from the river."
Swiftcurrent Glacier from Trail
Swiftcurrent Glacier from Swiftcurrent Trail. Glacier National Park.
Sperry Glacier - Panorama
The 1913 image of Sperry Glacier shows the thickness of the glacial ice that once covered the Sperry basin. Now, at approximately 1/3 of it's maximum area, Sperry Glacier continues to recede at a rapid rate. It is one of the glaciers that USGS scientists are monitoring as a benchmark glacier.
Sperry Glacier
The northwest portion of Sperry Glacier once spanned Comeau Pass to the base of Edwards Mountain.
