Fume, thick enough to require a gas mask, issues from cracks between June 25 spatter cone and south base of Pu`u `O`o, visible at upper right edge of image. Sulfur lines many cracks.
Aerial view looking northwestward at Pu`u `O`o. Lava flows surround lighter cone, made of scoria and spatter. Part of crater visible in upper right; largest fume column comes from East Pond Vent. June 25 cone, shown in left image, is barely visible at distant base of Pu`u `O`o.
Sluggish lava emerges from elephant-skinned toe of pahoehoe, 1540-foot elevation, Pulama pali. Such sluggish lava is common in this area and reflects somewhat cooler temperature than for the breakouts shown above.
