View of the 61g flow field, from Puʻu ʻŌʻō (visible on top, left horizon) to the westernmost ocean entry at the coast, where lava spills into the sea, creating a lava delta. Fume emanating from the flow field—on the coastal plain (above the ocean entry) and high on the pali (cliff) in the far distance—delineate part of the active tube system that carries lava from the Puʻu ʻŌʻō vent to the sea.
