What are the little piles of dirt?

I figured worms. This is a new to me yard. I've seen a few in other yards I have but not like this.
I've got moles in other yards so i know them.

Definitely night crawler castings. We have them in our yard.

Those are potholes, not mounds of dirt, lol

I submit that depends on the stretch of Highway.

I thought the foot or more across were called Oklahoma Roads.

What I don’t understand is why the highway department doesn’t take all the humps and put them in the dips to smooth out the road.

In the yard? Theres hundreds of them all of a sudden. I've seen a few in the yard before but this years ridiculous.
Ants? Worms? What?

I have the same problem, they seem to show up just after a rain. Then it showed up again a week later just after another rain? I looked this up. and it seems to be crayfish! Not The crawdads you find in streams but a different type? I had noticed this before but just two, or three holes at a time, in the lowest point of the lawn, where water stands, now they are all over the lawn? INVASION of the CRAYFISH?

That would throw the Earth off it’s axis.
