Detailed Description
Pu‘u ‘Ō‘ō started as a cinder and spatter cone in the 1980s, but over the past 30 years flank vents on the cone have produced stacks of lava flows, creating a broad shield around the cone. This view looks north and shows the shield shape clearly. Mauna Kea Volcano can be seen in the distance.
