This paper presents the results of a recent documentation of the rock art panel called “Runohällen” in Gerum, Bohuslän (RAÄ Tanum 311:1). The documentation was conducted using photogrammetry and analysed using a new documentation method. It was possible to identify several new motifs, updating the record from previous documentations. During this work a petroglyph previously identified as an axe stood out through an elongated and as of yet unexplained feature. It is argued that this motif is indeed an axe, but converse to the older interpretation, it is suggested that the motif is turned “upside-down” when compared to the major-ity of petroglyphs on the panel. Several interpretations are considered, but it is thought most likely that the carving had an antagonistic purpose.
