The Bear Glacier on the Kenai Peninsula along the Gulf of Alaska seen by the IKONOS satellite took this on August 8, 2005. This image shows the ablation zone where the glacier is primarily losing ice. Upslope from the lake, the foot of the glacier is riddled with crevasses - cracks in the ice caused by the glacier's movement over a rough surface. Down the middle of the glacier run dark gray stripes. As a glacier moves, it picks up dirt and debris from the rocks it passes. When two glaciers merge, as they have here, the dirt and debris they carry form parallel stripes, or medial moraines, on the ice surface. (IKONOS satellite image courtesy GeoEye) #
