The highly weathered assemblage comprised a cluster of two “cup and ring” motifs with at least eight additional cup marks pecked on a small basalt boulder located on the summit of Ambra Crater (also Mt. Ambra), a potentially significant place because it has provided an elevated viewpoint across the denuded Upper Wahgi Valley landscape for millennia.Denham was supported by an OPRS Scholarshipapplication/pdfen-AU© 2021 Oceania Publicationsrock artPapua New GuineaWestern Highlandsengravings202110.1002/arco.52352022-04-03
