Ban Nam Nai. According to Van Den Bergh et al. the jars in Group I are very small and are buried up to their rims in the soil, in contrast to those in Group II and III, where the jars rest on ground surface. The groups are positioned on two hills on the fringe of an upper valley and are separated by a new road. The area of Groups II and III was recently used for agriculture and the jars which are not buried are broken and damaged. A total of 17 granite jars were recorded.
