A new breakout started yesterday afternoon (9/30) near Kalapana. By this morning, the flow had nearly stopped, its front (shown here) barely creeping forward through grass and sparse forest.

The breakout was from the side of the lava tube feeding the Puhi-o-Kalaikini ocean entry a few hundred meters (yards) upslope from where the tube crosses Highway 130. The photo is taken from the crest of the tube, which forms a low ridge snaking through the flow field in this area.

This adolescent chick, hatched and raised at the USGS Patuxent Wildlife Research Center, is one of ten whooping cranes being released in Louisiana in February 2011. It is a milestone for the state and for the birds, which have not lived in the state since the 1950s.
