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. They visited sixteen caves and surveyed eight of them. Photographs from the expedition can be found on the CDS09 Website

Authorities are investigating a complaint that national police chief Seripisut Temiyavej has encroached upon a cave within a forest reserve and converted it into a karaoke room, Natural Resources and Environment Minister Anongwan Thepsuthin said Friday.
The cave is located in Thong Pha Phum district, Kanchanaburi.
"I hear that the cave is like a personal entertainment centre complete with the latest audio system," she said.
Anongwan said any encroacher would be prosecuted to the fullest extent of the law.
