This abstraction of  salt + coastal granite rocks was made whilst  I was on an afternoon poodlewalk with Maleko amongst some coastal rocks west of Petrel Cove on the southern  Fleurieu Peninsula of South Australia.  

It had been a hot summers  day and the small pools of water  that usually lie amongst the granite rocks from the  high tide in the morning had evaporated. I made a number  of studies of these salt abstractions that afternoon.
