Fallout on flank of Pu'u Huluhulu from inclined fountain Oct. 20, 1970

Fallout on flank of Pu'u Huluhulu from inclined fountain of October 20, 1969. The high vertical fountain was briefly diverted toward Pu'u Huluhulu when a blockage developed at the vent. Observers at the viewing platform (on the left-most peak on the skyline) scrambled to escape, but after several minutes the fountain righted itself. Fallout from the inclined fountain killed all vegetation where it landed, and some was still so hot that it welded and began to flow downslope, creating the glacier-like crevasses visible in the photo.
