B, Part of an ASTER scene showing Llewellyn (top left) and Tulsequah (lower right) Glaciers. C, Map showing water and glacier features and created from partial ASTER scene shown in B using an enhanced maximum likelihood supervised classification of three derived bands (after Sidjak and Wheate, 1999).
