ARTEFACT OF THE WEEK: Today’s artefacts depict ventifacts from Waiinu Beach near Waitotara. Ventifacts are stones that have been formed into faceted shapes and textures by strong winds and fine-grained sand. They are found in only a few places, including Antarctica, the planet Mars and South Taranaki. The grooves or striations in the rock indicate the wind direction. Ancient ventifacts can show us what the weather was like millions of years ago, provided the rocks are not moved. If you know more information about these artefacts that would be useful for our catalogue, contact the museum on 0800 111 323 or email@example.com, Aotea Utanganui Museum of South Taranaki Heritage Collection, with reference to: 2010.008.
