"Rootless" lava shields are those built over a lava tube, as opposed to those which develop over the vent. This rootless shield was built over the past week, and hosted a lava pond at its summit. Overflows from the pond cascaded down the steep flanks.

Thermal image of Kilauea viewing area
A closer view of the County viewing area, looking northeast. Again, the thermal image is shown together with a normal photograph. Recently emplaced flows, from the past several weeks, are light red (center of image). The currently active breakouts, just 250 yards northwest of the road, show up as white and yellow.

Aerial coastline of Kilauea
An aerial photograph looking west along the coastline of the current flow field. The Ki entry continues to produce a small plume, which is distributed along the newly formed delta. The color change in the ocean near the entry is due to the wave erosion of material from the delta and the lava itself.
