Hopefully Murf will pick this thread up cause he knows lottsa stuff about this.

I have a couple of BFRs here. I did not build a footer for any of them. So every year they sink a little. Every 3-4 years I hoist them up and put some #2 stone under them and relevel.

I can not figure it out every year the frost brings stones and rocks closer to the surface pushing them up. Or as some people say growing rocks. Since that is true why aren't mine on their tippy toes?

Oh yea back to the thread. I'd make sure your rocks have something solid to sit on and built below the frost line. You could use lottsa rocks for a footer also and tie them all in to your terracing. You will want something behind them to hold the soil out of them either lottsa smaller rocks mortored in or a concrete wall. Frost will push and heave the stuffing out of a nice design with out solid footers and retainment.

A good rock is one somebody else picks! Harvey
