Sketching the Historic Kangaroo Point Cliffs, from the City Botanic Gardens, with the Brisbane City Sketchers.
It was a lovely morning filled with laughter and fun, and some drama to boot. (A man got stuck on the side of the cliffs across the river from us) I rang the police and he was saved.

These lavas and pyroclastic rocks of the cliffs were deposited in the Triassic Period about 230 million years ago and filled an ancient river valley. These rocks were known as porphyry and later became known as the geological unit called the Brisbane tuff.
Records indicate that it was Captain Patrick Logan who first opened a quarry to supply stone to his building works as early as 1826.  It was the female prisoners who were required to quarry the cliffs.

The Cliffs are heritage listed and  are now a playground for RiverLife..
