Alveolar or Honeycomb Weathering of Coastal Cliffs at Bondi Beach, Sydney, Australia. Alveolar or honeycomb weathering of Hawkesbury Sandstone (Triassic Age, 190-225 million years), exposed along Bondi Beach coastal walk is a fantastic structural feature where one can stop to admire and enjoy nature's creations. Alveolar or honeycomb weathering, also known as fretting, cavernous weathering, stone lattice, stone lace or miniature tafoni weathering, is a type of salt weathering common on coastal and semi-arid granites, sandstones and limestones (Mustoe, 1982). This photograph shows a close-up view of alveolar or honeycomb weathering of Hawkesbury Sandstone exposed along Bondi Beach Coastal Walk in Sydney, Australia. Also note the interconnected solution caverns throughout the sandstone. (Photograph by P.T. Hanamgond, Department of Geology, G.S.
