Lava Flow Activity

Activity on the active flow field has been dominated by rootless lava shield construction for the past several weeks (Pu`u `Ō `ō). The main shield, seen here, is topped by a lava pond that feeds overflows down the sides of the shield. Successive overflows slowly build up the height of the shields. At the time of this photo, a second shield was also active out of sight to the right.
