Geology
The Beung Kiat Ngong Wetlands are located in a large plain that descends from the Bolaven Plateau, which is an old volcanic (presently inactive) mountain. Large numbers of different sized rocks are scatted throughout the area, many of which originated from volcanic events in the past, such as volcanic explosions and lava flows. Some very rocky areas exist here and are called ‘lang’ in Lao language.
