The margins of the large ice field (white area) in the center of the picture show many valley or alpine glaciers descending from the higher elevations of this section of the Coast Mountains (Canadian-U.S. Border). The ice field straddles the Canadian-U.S. border at 57 degrees north latitude. Mt. Burkett (9730 feet - 2966 meters) and Kate’s Needle (10023 feet - 3055 meters) are just two of the many ice covered peaks, known as horns, that are observed in this image. Clouds obscure the Stikine River Valley on the east side of the ice field (top of picture).
