View from Phou Pha Mane mountain, the highest peak in the Phou Hin Boun Biodiversity Conservation Area in Khammouane Province of Lao, PDR. Gorgeous limestone forest with thousands of karst pinnacles. [NOTE: Lot of cool flora and fauna live here. In particular, the Laotian rock rat or kya nyou (Laonastes aenigmamus), belonging to the ancient fossil family, Diatomyidae, thought to be extinct for 11 million years].
