Telephoto view of one of the spattering sites on the west pit lava pond margin, in Pu‘u ‘Ō‘ō crater. Molten spatter is being thrown in the air, and landing on the thick pond crust. Solidified pieces of spatter around the source on both the pond surface and the ledge above have a mottled appearance. Photo taken Wednesday, November 22, 2017 courtesy of USGS/HVO
