LaosRésumé : Northern Laos is virtually unknown to speleology. Only a few reconnaissance projects and three caving expeditions were conducted prior to 2005 in the province of Luang Phrabang: a Dutch expedition (AMIS Laos expedition 2000, with a preparatory trip in 1999) and two German projects in 2002 and 2003/04.
The 2000 AMIS Laos project produced approximately 7,300 m of surveyed passage from 15 caves, including the 2,070 m long system Tham Khan-Pageo (Muang Ngoy, Nam Ou Valley, Ngoy district - now open to tourists), the 1,433 m long Tham Gnai (Nan District), and the 1,028 m long Tham Pha Kouang (Nong Khiaw, Ngoy district), as well as the deepest cave found to date in the region: the -105 m deep Tham Thia (Nan District).
The two German expeditions produced 5,564 m of mapped cave passages from 34 caves, the longest of which was Tham Loum (Xiang Ngeun District) with 1,598 m of passage. Finally a joint Dutch-German project was conducted in February 2005. In the area of Phou Khoun south of Luang Phrabang several caves were linked to form a 2.65 km long cave system (Tham Seua-Nam Lot). A new caving region was visited around Vieng Phouka in the Luang Nam Tha province close to the Thai and Burma borders. The first investigations resulted in significant findings such as Tham Pasat (Tham Nam Mai) at 1,490 m, Tham Nam Eng (Fossil Cave) at 3,120 m, and Tham Nam Eng (Resurgence Cave) at 3,460 m.
Overall, roughly 24.3 km of cave passage has been surveyed to date in northern Laos. This report contains an overview of all visited caving regions with detailed maps and cave descriptions. Additionally, one chapter is dedicated to biospeleological investigations.[n° ou bulletin]Exemplaires(1)
