Mahalo means thank you. About 250,000 nene existed on the islands when Captain Cook arrived in 1778. By the mid 1940's only 50 birds remained. Captive breeding programs have increased the number of nene to about 600. Pahoehoe is the Hawaiian word for a common form of lava.
Pahoehoe lava is characterized by a smooth, billowy, or ropy surface.
A ropy surface develops when a thin skin of cooler lava at the surface of the flow is pushed into folds by the faster moving, fluid lava just below the surface. Pahoehoe flows can evolve into lava tubes. It is the name of an active cinder cone on the Kilauea Volcano.
