proposed on the basis of various lines of evidence that the crater lies buried beneath the Bolaven volcanic field in southern Laos. In 1991, Wasson et al. studied layered tektites in central Thailand and explained the lack of a large recognizable source crater by occurrence of small, diffuse, multiple impact event spread out over the region.
