Cup marks on Ambra Crater: a new engraving site in the Western Highlands of Papua New Guinea

Abstract

We report an unusual example of rock engravings in an open context in the Highlands region of Papua New Guinea. 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. Show more
