Smooth surface of new shield growing above the 2240-foot skylight on the main tube from Pu`u `O`o. A small breakout is taking place from a crack in the inflating shield.
Volunteer geophysicist uses VLF (Very Low Frequency) instrument to measure flux in lava tube near the new shield in background. Note the gas mask, necessary in this obnoxious area. A rootless shield is a pile of lava flows built over a lava tube rather than over a conduit feeding magma from within the earth. Rootless shields along the tube system commonly have a flat top containing a shallow lava pond.
Eerie view of a family of hornitos. An existing old-timer (right) at site of the former 2300-foot skylight has been joined in past week by two youngsters. Note the two figures between the two right-hand hornitos.
