Top: The episode 55 vent built this spatter cone soon after it became
active on March 28. The cone is located on the west flank of Pu`u `O`o
cone--the brown-colored cinder covering the flank is visible in lower left
of photograph. Lava from the spatter cone filled the pit on the left; note the recent overflow of pahoehoe from the
pit. Bottom:
Same spatter cone, sending festoons of lava over its rim and down
its
sides.
