Rocks 9-17 LRJCD – Rocks with holes made by natural erosion, and not resulting from any action by marine invertebrates such marine worms, sponges or bivalve molluscs. Probably classified as a type of honeycomb weathering and caused in part by exposure of sandstone type rocks to salt water and the elements.

  1. You might like to try to access the article by Nick Doe. What makes holes in sandstone on the internet. He discusses these features on Gabriola Island BC. The article was published as follows:
    Citation: Doe, N.A., What makes holes in sandstone, SHALE 9, 2d ed., pp.12–40, August 2004.

    Google search doesn’t allow me to copy the URL here for some reason – it just downloads the pdf paper but I think might work.

    Hope this is of interest.

  2. Thank you for this information, Paddy. I was aware of the term tafoni but thought there was a distinction between them and honeycomb weathering to do with scale – with tafoni being on the larger size.


  3. This is really interesting. Thank you so much for the reference. It will fill a great gap in my knowledge I am sure. Gabriola Island seems to be a fascinating area too.
