Christmas Island itself is an uplifted, composite, reef-carbonate island that has a volcanic core; generally speaking this means that the malignantly formed island surging out of the Indian Ocean is a caver’s paradise.
To the north of the island, south west of Flying Fish Cove, hidden secretly amongst the jagged and battered limestone coastline, lies what almost appears to be an aberration of the mind 3,500 meters in length.
A 'significant cave' known to the local people as the Lost Lake.
It is no easy conquest to journey to the entrance of Lost Lake, the only means of transport is via boat.
Vadose and phreatic waters meet at the caves coastal entrance, from this point it is a seven hour transit across flooded tidal, joint controlled passages and volcanic rocks beneath the plateau until we meet with the phantasmagoria chamber.
1. a sequence of real or imaginary images like that are seen in a dream.
"what happened next was a phantasmagoria of horror and mystery"
The phantasmagoria is a large collapse dome chamber with phreatic spongework walls. Crystal lines every surface within the chamber and shimmers radically with light from our head lamps, the refraction of light trick into a kaleidoscopic allusion.
No one person can really know what to expect when setting off on a caving expedition to the centre of Christmas Island, and this could not be more true of the early caving pioneers who first descended into the island heart land. People such as David Powell, Ray Bishop and Les Smith, local speleologists discovered many of the islands cave and sinkholes during the exploration for permanent water sources for the islands growing population. Strangely enough given the high annual rainfall the Island has no permanent surface water source.
