Hudson Bay Mountain Glacier Extents:  1981-2005

Two glaciers, Toboggan and Hudson Bay, flow northeast on Hudson Bay Mountain just a few kilometers from the town of Smithers, British Columbia.  Some of the ski trails of Hudson Bay Mountain Resort are visible at the bottom center of the image.  This is a false color composite (bands 4, 3, 2) satellite image: Ice and snow are readily visible in such images, whereas vegetation appears red.  The 2005 glacier extents were derived from this image, while the 1981 extents were mapped from aerial photographs.
