After the volcanic activity of the 2000s, the thickness of the glacier continues to increase at a slower rate of per year and the glacier continues to advance at 3 ft (1 m) per day. The latest aerial imagery taken in 2012 shows that the glacier has entered the upper reaches of the Loowit Creek canyon and the headwaters of the creek. Ice mixed with rock debris now spills into the canyon and the creek has been pushed to the east. Nearby, on the slopes of the eastern crater wall, the glacier touches one of the rock glaciers and the glacier is very close to merging with the other rock glacier. A medial moraine can be seen at the interface of the eastern and western arms of the Crater Glacier.
