Patches of exposed granite bedrock around Cue, in central Western Australia, that have been smoothed by being used for grinding are described and compared with portable grindstones recorded in the same region. Patches had rarely been reported from this area before, although they have long been recognised in the Pilbara. The extension into the southern half of Western Australia of a type of evidence for past human behaviour rarely identified there is significant. Two much- debated questions are also considered, but left unresolved due to insufficient data: whether there is a morphological difference between grindstones used to wet mill grass seeds and those used for dry grinding hard seeds and whether the juxtaposition of grinding, generally considered to have been women’s work, with rock carvings, usually assumed to have been made by men, is socio-culturally significant.
