Halema‘uma‘u lava lake and channelized flow on pali

Southerly winds afforded a rare view of the south side of the Overlook vent in Halema‘uma‘u Crater, within Kīlauea's caldera. The collapse crater that defines the opening of the vent is about 160 m (~525 ft) across and 80 m (~260 ft) deep. The fence for the old tourist overlook is faintly visible at the upper right side of the photo.
