Rocks and Coffee "cracks"

By now you know how weird I am about looking at the effects of pressure on things.  I can study rocks endlessly for the effects of the power of water on them.  And then, I can be amused by the imagined "cracks" in my lovely cup of Cappuccino!

 these were taken near San Antonio on the edge of a river.

Limestone is everywhere in this part of the world.

I love the bore-holes the water makes.

...and then there is my delicious cuppa!
