Siyeh Glacier: upper - 2015 satellite photo, lower - 2005 aerial photo

Siyeh Glacier (upper – 2015 satellite photo,  lower - 2005 aerial photo). The glacier margin is more clearly identified in the 2015 image  because seasonal snow is persisting on the ice and rock debris atop the ice can be more clearly seen than in the heavily shaded 2005 image.
