Tessellated rock platform.
Wind eroded portion of cliff face showing difference between exterior and interior texture of the soft sandstone.
Small drop-stone, ferrous joint, casuarina needles and faint fossils.
Where a drop-stone landed and left an impression.
The wind here has blown out a vertical flue adjacent to the iron-rich joint.
TC journal entry
Started at the boat ramp near Dillon Street and headed south along the rocky shoreline. First stop was a good perching spot on the edge of whiter siltstone that displayed the tessellated fracturing but was further weathered so resembled the rounded form of half-risen baker’s buns. Discussed Permian rocks and how they got here (Permian is typically the oldest rock of Eastern Tasmanian region) and consulted the geology map for context. Along the rock platform a bit to the south we came across a clear flat tessellated area where the perpendicular/orthogonal grid was particularly evident under our feet and up the face of the cliffs.
We talked about how not all sandstone is Permian. Some, such as that found in New Town is Triassic (more recent) and its whereabouts is shown green on the geological map.
Example of the parallel jointing continuing up the cliff face.
