A four person French expedition from the Societe Speleologique Ariege - Pays d'Olmes, led by Philippe Jarlan, was in Nan and Chiang Mai province from 12 July to 5 August 2008.
From the Bangkok Post of 10 June 2008 - a magnificent example of a journalist not having a clue about the subject of their report. Thanks to Liz Price for bringing this to my attention.
