Pool deck post holes

I'm building a deck for a 30 ft above ground pool. The ground where I'm digging has about 6 in of soil then hard packed clay. I can't imagine that clay is going anywhere. I know code wants me to be at least 36 in down, but in reality if the holes are only 16 in deep and I place pavers and concrete in the bottom and concrete around the post will this cause me trouble in the future? I live in NY climate wise. The clay in the soil is like a rock, with the post hole digger I'm making about a quarter inch of headway each time.

Code is there for a reason and it represents minimums only. Additionally, while I would not bury wood like this, the normal process is for at least 1/3 of the post to be below ground for stability.

May I ask what you would suggest as an alternative?

The depths are there to get the posts, or any kind of footings, below the frost line so that the posts/structure do not heave in the winter. There really is no alternative to something being installed into the ground that supports a deck/garage/house!

My alternative would be concrete footers at the frost depth with brackets for the posts embedded.
