A complex configuration has been in place deep within the vent cavity in Halema`uma`u crater. Lava upwells in the west portion of the vent floor (upper left of photograph), feeding the small, crusted, circular lava lake. In the east portion of the vent cavity floor, lava upwells (out of view, towards the lower right of the photo) and feeds an elevated and swiftly moving lava stream, which flows west and cascades over a small cliff into the lava lake.
