The minimum footing depth in my area is 12".

I dug a 24" footing and put in 2" of gravel and 10" of concrete. The post will sit on top of the concrete footing, and the hole back filled with dirt.

Is frost heave a risk if the POST is not below frost line, or only if the concrete footer under the post is not below the frost line.

I would think it is a risk since the post is just sitting on top of the concrete footer and could be heaved up, but maybe not.

Please advise!

If you manage to get water or dirt between the two but only if you get weather below freezing for the longest time you have in the last many years. I think you are good for frost worries.

Why didn't you bring the concrete to the surface and keep the post out of the dirt and rot conditions.
