Lava spout
A tongue of lava emerging from a crack in the cooled rock of earlier flow. It poured forth fairly quickly at right, adding to the molasses motion leftward. The surface of the slower-moving lava was cooler and darker, perhaps beginning to form a crust where molton stone met air, cloven by a trickle of rejuvenating heat from the outbreak. Taken in Hawai‘i Volcanoes National Park on March 7, 2003.
