Looking down into the vent cavity of the Halema‘uma‘u Overlook vent. The black ring on the walls surrounding the lava pond is a high lava mark, outlining the height the lava rose during a recent rise/fall cycle.

Photo of vigorous boiling of the lava surface in Kīlauea's summit vent following vent wall and rim collapses earlier in the day. The rim of the vent on the floor of Halema‘uma‘u is about 150 m (yards) across. The lava surface is about 100 m (yards) below the rim.
