I used to live in a town called Lakeside,not too far from Ramona.As a child we would play on boulders that had the same grinding holes in them ,as you described.
They were neat!

Yes, I know Lakeside well, LOL, or did, I left San Diego in 1969.
Those rocks are interesting, to me, for the simple reason that they had them every place on their travels.
We talk about which mill to buy and they simple asked for the grinding stone.
Welcome to the thread.
