The vast extent of the Blue Dragon lava flow, forming the flat area in the middle of the photo, can be appreciated in this view from Big Cinder Butte with Big Southern Butte in the background to the east. The Blue Dragon flow, the largest volume lava flow at Craters of the Moon, covers 280 km² with 3.4 cu km of lava. The flow was erupted about 2075 years ago and covers broad areas as far as 25 km to the east and 15 km to the SW of its vent area.
