Cuttagee is south of Bermagui. We only stopped off there because there was a lagoon that I wanted to photograph, but we found these (tested for hardness) quartz veins in a sort of sandstone, and above, some interesting honeycomb weathering in the headland at the northern end of the beach: we could access it at high tide.
Next time: The Pinnacles, and Myrtle Beach, which has an unconformity, as it lies at the base of the Sydney Basin.
