A look into Halema‘uma‘u Overlook vent shows depth of the lava pond

The lava pond in the vent cavity of the Halema‘uma‘u Overlook vent during the rise phase of a rise/fall cycle. In this photo, the lava pond is 95 m (312 ft) below the floor of Halema‘uma‘u crater. When the pond level is high there is very little fume, allowing for unusually clear views.
