Micromorphology has provided evidence for the deliberate movement and deposition of cremation deposits at Na Clachan Aoraidh (Ellis and Ritchie 2018), as well as the phased construction of the mound at North Mains (Romans and Robertson 1983a). Phosphate analysis conducted at the same site was able to indicate the likelihood that the barrow had covered burials but was not supported by further investigation and alternative inputs of organic material could not be excluded (Pare 1983).
