SPELEOLOGY IN WESTERN AUSTRALIA
I recently started doing speleology (caving) again. I used to be very active back in Belgium, but largely gave up caving when I went to live in Zambia. Caving in Belgium is often a claustrophobic experience, with a few wonderful watery caves as well (see pics below and more pictures on my picasa web pages (here))
After my Belgian caving came to an end, I did spend some time caving in Sardegna (Italy) with my brother. Sardegna has some very nice, long and big caves, as well as well-developed canyon systems worth exploring (pictures below)
I've now joined the Western Australian Speleological Group (WASG) who are quite active in the Margareth River and Yanchep area, and sometimes conduct excursions elsewhere. The group is more than just a recreational organisation, and engages in a lot of activities including conservation, mapping and research.
