Looking south across Pu`u `O`o

Looking south across Pu`u `O`o. The north side of the cone consists of oxidized spatter, cinder, and ash. Lava flows that spilled from the crater in the late 1990s coat the east rim of the crater. Lava lake erupted in April forms crater floor. Most fume comes from January 2002 vent; East Pond Vent evident near east end of crater. The high southwest rim is made of spatter and cinder, some agglutinated. In the distance is the fuming area of rootless shields.
