Fofo,
Very interesting, but there's got to be something wrong with
your entry for France. If France has 43 caves longer than 15 km,
then it must have way more surveyed passage than the 23,266 m you
gave. Just two such caves would give at least 30,000 m, and 43 would
give a minimum of 645,000 m. Checking Bob Gulden's long cave list
<http://www.caverbob.com/wlong.htm> shows that the longest cave in
France is 105767 m by itself (Reseau Felix Trombe / Henne-Morte). I
didn't take the time to add them all up, but perhaps you dropped a
digit or two.
I think this would make a good article for the NSS News!

Hi!
A few days ago there was a question in the Spanish language list
Tlamaqui about which country had the most surveyed passages in the
world, so as a quick estimate I took the list of caves with more
than 15,000 m and grouped it by country. Bill Mixon found the
information interesting and suggested posting it here too. Here it is.
