Today I was up the coast in San Simeon to watch a friend fly a model glider. It was a windy day, and they were proacticing for a competition tomorrow. I watched ahwile and then looked for rocks.
I found this very smooth (on one side only) unusual rock -- it feels and has the sheen of flint and I am wondering if it was actually worked on at one point. If it were, of course I would need to return it to the place found -- but after examining it, I decided it was not a tool after all, but a womderful rock to select for today.
Measures approx 1 1/4".
