We are in mountains with very low temps in the winter. Used 4 inches of sand and layed the bricks on that, easy to level and has never moved or heaved in spring.

Thanks for the feedback
I plan to build my wall about 2.5 to 3' high & back fill with gravel / soil.
Frost heave is not a problem, mid Texas, moderate temps.
From what you describe, my plan is overkill.
