National Rock Glacier, Alaska

View Original Image at Full Size

Figure 2 National Rock Glacier, Wrangell Mountains, Alaska. There is no glacier visible at the headwall of the cirque here. There probably was a small distinct glacier below the cliffs but only remnants now remain. The glacier ice is now buried under the slow-moving surface debris. The debris input from the headwall and sidewalls form what are essentially lateral and medial moraines.
