A view of the northern Overlook crater wall, through passing fume. The lake surface (lower left in photo) was about 22 meters (72 feet) below the crater rim (upper right in photo). The uppermost section of the crater wall is formed by stacks of thin overflows from mid-2015. The main section of the wall, with a light pink color here, is the older portions of the Halema‘uma‘u Crater floor, formed from lava flows that filled the crater decades ago. At the base of the wall, spattering from the lake has deposited a thin black veneer of lava on the crater wall. Sometimes these spatter deposits built out small ledges, and form bulbous protrusions (center of photo) when the lake level drops. Photo taken Sunday, June 4, 2017 courtesy of USGS/HVO

This photo from a video clip shows HVO geologist Tim Orr sampling lava from an active pāhoehoe breakout on the episode 61g lava flow. The chemistry of these lava samples provides information on the magma plumbing system. Sampling has been a regular part of monitoring Kīlauea Volcano's ongoing Pu‘u ‘Ō‘ō eruption.
