unusual facts about Craig Challen


Cocklebiddy, Western Australia

In 1995 South Australian cave diver Christopher Brown went another 20 metres further again, and in late 2008 much of the cave's more distant regions were explored, mapped (using radio-location "pingers" designed and operated by Ken Smith) and videotaped by Craig Challen and Dr Richard ("Harry") Harris et al. using hi-tech rebreather technologies.
