 Since 2004 , new glaciers have formed on the crater wall above Crater Glacier feeding rock and ice to Crater Glacier below . In addition , there are two rock glaciers to the north of the eastern lobe of Crater Glacier and one north of the western lobe . Two of these rock glaciers have merged with the Crater Glacier , with one on the west and one on the east . The other rock glacier on the eastern slopes of the crater wall is very close to touching the glacier .
