Satellite image of glaciers and icefields
Location:
Bylot Island, Nunavut, Canada;
NTS
38C Bylot Island & 38B Pond Inlet;
False-color image from LANDSAT 1 satellite. Image E 1748-16544 shows the extent of glaciers and icefields on Bylot Island and adjacent Baffin Island (Pond Inlet to the east and Eclipse Sound to the west separate the two islands; town of Pond Inlet is also indicated). Light-colored areas along the coastline at the top of the image represent areas dominated by vegetation-free cabonate debris transported onshore by a major glacier that flowed down Lancaster Sound north of Bylot Island and expanded as it emerged into Baffin Bay during the last glacial maximum ( Klassen, 1993; and Klassen and Shilts, 1987). Most tundra flora on the island are acidophilic and will not tolerate the alkalinity of the soils on these carbonate-rich sediments. Labels on individual glaciers are derived from Area 46201 on the Baffin Island Index Map (Glacier Atlas of Canada, 1972).
