This is a steep aerial view of the small lava pond at the top of the spatter cone on the northeastern side of the crater floor. Lava in the pond flows directly into a lava tube which is supplying the active flow northeast of Pu‘u ‘Ō‘ō. The head of the tube, marked by fume, extends from the pond toward the left side of the photo.
