Aerial views of the active rootless shield at the 2220-foot elevation, along the master tube carrying lava from Pu`u `O`o to the coastal flat. 150-200 meters across, lava oozes downslope toward camera. Already sulfur deposition is extensive, making the hornito look prematurely old.

Aerial views of the active rootless shield at the 2220-foot elevation, along the master tube carrying lava from Pu`u `O`o to the coastal flat. 25-50 meters wide, a small bubbling fountain feeds lava toward camera along right side of view, while smooth crust on a lava pond is slowly breaking and sinking left of the fountain. Note the developing crack in the crust (left center) with incandescent lava oozing from it. The crust sinks because the underlying bubbly lava is lighter and more buoyant. Two columns make up the hornito. Already sulfur deposition is extensive, making the hornito look prematurely old.

New, spirelike hornito at 2240-foot elevation, formed in past week just upslope from the old 2240-foot skylight along the lava tube below Pu`u `O`o. This hornito is unusually steep and narrow, almost a chimney.

Looking northwest at the 2300-foot hornito. This one began to form between January 4 and January 11, on yet another older hornito. Compare with views on January 17 for changes in past week. Blue box is about 50 centimeters long.
