How to prevent groundhogs from digging old holes

I have groundhogs moving in every year. After trapping and relocating I will fill the hole with dirt. Somehow new hogs find the old hole and excavate it. I'm guessing the fill is softer than surrounding dirt so it's easy to dig up.

How do I prevent or discourage re-digs? I'm thinking of mixing the dirt with broken glass in my next fill.
