We spent a fantastic couple hours underground this morning in Ruakuri
Cave. Very pristine setting, with evidence of both active formation
and dissolution. The glowworms (Arachnocampa) were a highlight with
their delicate silk threads set from the ceiling to catch prey. They
illuminated some ceilings like constellations of stars in the night
sky. The rafting on the stream flowing through the cave looks
interesting for next time.
