Panoramic view of the breach through the north rim of the maar crater lake in Aniakchak caldera. Geologist Tina Neal (left) and NPS Resource Manager Troy Hamon (right) for scale. The lake level prior to the flood event was at least 4.65 m (15.3 ft) above the stream where Neal is standing in this view. The breakout flood event occurred in late summer, 2010.
