Furthermore, it is the most famous Mekong River Civilization area and dominated by sedimentary rocks of the Khorat Plateau. Different erosion rate produces spectacular landforms such as potholes, rapids, stacks, cliffs, and cascades. According to inventory, characterization, classification and evaluation, these landforms are highly valuable elements to the regional heritage especially in the Pha Taem Cliff, which has outstanding prehistoric rock art.
