I started moving my composting wood chips this spring, and noticed that the middle of the pile is still frozen, but the outside is workable, why is that?
I can tell you that when we had no snow on the ground we had a -30F/-34C degree day.

I'm not sure where you're located, but it's likely the heat from the sun. If it froze during the colder months, it will take longer for the inside of the pile to thaw, whereas the outside of the pile has direct access to the sun. Once the whole thing thaws, then you'll start to see it beginning to get hot on the inside as the compost decomposes and generates heat. The frozen middle can't rot and generate that heat right now, just like food can't rot in your freezer.
