broken 1

I was playing along a stream on Tuesday. It was darn hard to climb down to with my oxygen tank and camera. It made me very short of breath. But I love water and running water is joyous.

I was picking up rocks and looking at rocks. This rock really interested me. Look at all the cracks. When the river is higher it would wear the rock down. In the winter the cracks might freeze. I thought this rock might be ready to break. What is inside?

This is for the Ragtag Daily Prompt: workshop.
