Detailed Description
USGS scientists make observations from the edge of Pu‘u ‘Ō‘ō's current crater. Pu‘u ‘Ō‘ō's high point - the northwestern remnant of the original cone that formed in the 1980's - is in the background. This higher ground provides a good perch for some of HVO's webcams, near upper right.
