Image: Backed artefacts from Mussel Shelter, NSW central coast
Backed artefacts made from silicified tuff, a stone material that is not available in the Upper Mangrove Creek catchment and thus these artefacts and/or the stone from which they were made were imported from regions such as the Hunter Valley to the north or the Nepean River in the south. Scale bars are 1 cm each.
